“We should refactor the whole thing…” I've heard this line more times than I can count — and honestly, most of those refactors failed. Not because refactoring is a bad idea. But because they were done wrong. Here are the top reasons I’ve seen (and experienced): No clear target architecture “We just want it cleaner” is not a plan. Lack of test coverage If you don’t have a safety net, every change is a risk. Big-bang rewrites Trying to change everything at once = chaos. Team misalignment If everyone has a different definition of “clean,” good luck. ✅ How to Do It Right If you want your refactor to succeed, start with these: Define the end goal What will the architecture look like after refactoring? Refactor incrementally Small, focused changes are easier to test, review, and roll back. Write tests first Ensure you’re not breaking things while cleaning things up. Align the team on standards Agree on patterns, formatting, naming — everything. 💡 My Take The best refactors I’ve seen had these 3 things: A clear vision A solid test suite A well-communicated plan Refactoring without those? You’re just rewriting code and hoping for the best. Have you ever done a big refactor? Was it painful or satisfying? Did you have the plan and tests? Or was it more like “rip it out and hope”? Let’s share some refactor war stories in the comments. 👇  ( 6 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My fascination with real-time web applications began during a project where we needed to push live updates to thousands of connected clients simultaneously.

Vibe Coding and the MVP Revolution: Buy Back Your Time, Impress Investors One of the most profound shifts brought by vibe coding is in how we create Minimum Viable Products (MVPs) and Proofs of Concept (PoCs). For founders, entrepreneurs, and anyone pitching ideas, the game has changed forever. Not long ago, building an MVP meant squeezing in late nights and weekends after your main job. Endless debugging, integration work, and feature building stole time from your family, friends, and personal life. Startup dreams often meant burnout before you even met an investor. Now, you describe your product vision in plain language, and AI turns it into a working prototype—fast: Speed to Demo: Build MVPs in hours, not weeks, so you can pitch ideas while they’re still fresh. Real, Testable Products: Show investors functional software, not just slides. Instant Iteration: Adjust for new feedback between investor meetings without sacrificing your life. With vibe coding, you no longer have to sacrifice your personal time to chase entrepreneurial goals. You can win investor confidence and have dinner with your family. That’s not just efficiency—it’s a lifestyle change. Vibe coding opens the door for non-technical founders to compete. With AI handling the heavy lifting, you don’t necessarily need a technical co-founder to get investor-ready. This speeds up innovation and widens access to entrepreneurial opportunities.  ( 6 min )

Vibe Coding and the New Era of Software: From “How” to “What” Vibe coding isn’t just another trend; it’s a paradigm shift in how software gets built. Popularized by Andrej Karpathy in early 2025, vibe coding is the art of letting AI handle how things are built while you focus entirely on what to build. Whether you’re a software architect, solo developer, startup founder, or tinkerer with a big idea, this changes everything. Vibe coding is an AI-first approach: Describe your vision—features, tweaks, or entire systems—in plain language. Let the AI write most (or all) of the code, often with minimal human review. If something breaks or needs changing, tell the AI what’s wrong, and it will handle updates. The codebase grows organically, without painstakingly managing every line. As Karpathy puts it: "You fully give in to the vibes, embrace exponentials, and forget that the code even exists." Your role becomes guiding, testing, and nudging AI in the right direction, sometimes just pasting an error message for it to fix. For architects, vibe coding is liberating: Less Drudgery: Manual bug fixing, syntax wrangling, and boilerplate fade away. Creative Focus: You get to think about architecture, design patterns, and product vision rather than low-level details. Rapid Experimentation: Prototype and iterate in hours instead of weeks. It reshapes the dev loop: Developers use AI to automate the mundane, freeing their attention for higher-value work. Architects set the “what” and “why,” while AI delivers the “how.” Vibe coding lowers barriers for entry into software creation. Non-technical founders, domain experts, and hobbyists can now ship working software without deep coding knowledge. That makes innovation more inclusive and the tech landscape more diverse. This is more than productivity—it's a cultural shift. We’re moving from craftsmanship-as-labor to craftsmanship-as-creativity. The grind becomes optional.  ( 6 min )

Preface Solidity is a strongly-types language, that means every variable must be declared with its data type Strongly type: The type of a variable cannot be changed after declaration A variable is automatically assigned a default value if not initialized. The default value of an integer is 0, boolean is false, address is the zero address. Most statements must end with a semicolon these are the most basic data types in solidity A boolean stores either true or false Only lowercase are valid! An int is a signed integer that can store positive and negative numbers. An uint is an unsigned integer that can only store non-negative numbers. you can specify the number of bits for an integer, from int8/uint8 to int256/uint256. for example, uint8 uses 8 bits, while uint256 uses 256 bits. if only int or unit is written, it defaults to int256 or uint256 An address stores a 20-byte Ethereum address. an int32 cannot be assigned to an int8, but a smaller type can be implicitly assigned to a larger type. for instance: int8 can be assigned to int32  ( 5 min )

A few days ago, a Reddit thread blew up about “the guy who consumed $50,000 worth of Claude Code tokens in 30 days on a $200 plan.” 👉 That guy was me. ⸻ How It Happened Claude Code currently offers a $200/month plan with: Generous usage (effectively no hard caps) Access to Ultrathink and Opus 24/7 background commands (added in v1.0.71) I leaned heavily on these features — but always within the official terms — to build real, user-facing products. By doing so, I unintentionally became the #1 token consumer worldwide. Some people on Reddit called this abuse. Personally, I don’t think so: I didn’t hack anything. I didn’t bypass limits. I simply used the service as it was offered. If anything, I see it as proof of how powerful Claude Code can be when you treat it not just as a coding assist…  ( 6 min )

AI for Non-Tech Founders: Start Here Jaideep Parashar ・ Aug 17 #ai #startup #webdev #beginners  ( 5 min )

We often hear developers glorify “short code.” The common belief is: fewer lines = better code. But in reality, short code does not always mean good code. In fact, sometimes 100 lines of code can be far better than 2 lines of code. Let’s understand this with a simple example: The 9 Balls Puzzle Imagine you have 9 balls, where 8 weigh the same and 1 is heavier. Your goal is to find the heavy ball using the minimum number of weighings. The optimal solution requires just 2 weighings: Divide the balls into 3 groups of 3. Compare two groups. Then compare 2 balls from the heavier group. In real life, this logic is simple when explained step by step. But imagine if someone compressed the entire logic into two ultra-clever lines of code. Sure, it might run. But will the next developer (or even your future self) be able to read it, debug it, or extend it easily? Probably not. The Illusion of Fewer Lines 2 lines of code: might look “smart” but can hide the actual thought process. It’s like solving the 9 balls puzzle by blurting out the answer without showing how you reached it. Impressive at first glance, but impossible to follow later. 100 lines of code: may seem long, but if written with clarity, comments, and step-by-step logic, anyone can trace the reasoning. Just like the step-by-step weighing process, it makes the solution transparent. Readability > Brevity Code is read far more often than it is written. When debugging at 3 a.m., you’d much rather have 100 clear lines than 2 “magical” ones. Short code is not always efficient code. Efficient code is code that is easy to understand, maintain, and extend. In other words: 👉 100 lines that anyone can understand are better than 2 lines that only you understand.  ( 6 min )

The Early Days: The Charm of Static Site Generation When I first built this site, Astro felt like the answer. As a developer, the concept of Static Site Generation (SSG) was a luxury. Amazing build speeds, fast site performance due to generating static HTML without JavaScript (by default), and a smooth developer experience (DX). Managing content via Markdown files within src/content/ was straightforward. Each article was a neat, structured .md file, all under Git version control. For a portfolio or personal blog with a few articles, this workflow was great: Write a new article in the code editor. git add . git commit -m "feat: add new blog post" git push Wait a few minutes for Netlify to finish building. The new article goes live. Simple, efficient, and very satisfying. As time …  ( 7 min )

A common misconception I hear is: “AI is too technical. I can’t use it because I don’t code.” The truth? Here’s how you can leverage AI as a non-tech founder, even if you’ve never written a single line of code. 1️⃣ Use AI as Your “Second Brain” Before you think about products or apps, use AI to make your thinking sharper.

How to Fix Apache Port Conflict The problem was that Apache failed to start because the configured port (5003) was already in use by another process. The solution involves identifying and stopping the process using that port, and then restarting Apache. The systemctl status httpd output provided key error messages: Address already in use: AH00072: make_sock: could not bind to address [::]:5003: This is the most critical error. It directly states that Apache cannot start because port 5003 is already in use by another application. no listening sockets available, shutting down: This is a direct consequence of the first error. Apache cannot create the necessary network socket, so it fails. Failed to start The Apache HTTP Server: The final status confirming the service could not be started. T…  ( 6 min )

Random people at work reach out to me to ask what I'm doing using so much of the Agentic AI service that our company has signed up for. I'm using more than most people at this multi-thousand employee company. I'm vibe coding. I hate the term. I'm not "vibing". I'm using my extensive computer science experience and insight to direct several AI agents on different tasks sometimes in completely different projects at the same time. They are working at the same time, I am not. I am working with one at a time -- and moving onto the next AI as the first is working on its task. Sometimes an agent works for minutes, sometimes it works for hours. Meantime, I'm working with other agents -- or getting coffee or chatting with colleagues. Just like working with a team of junior programmers, I give them some insights to get started and send them on their way. Then I check on what they produce -- because many times the work is bad. It needs correction. Rarely do I correct by changing code directly -- no, just as working with junior programmers, most corrections involve me telling the AI what to fix and then were to re-focus its efforts. These AIs are amazing. Some of the results are impossible for a person to produce in less than days -- but they are produced in minutes. Guess I'm vibe coding. It's particularly effective because I know how to code without AI. If you have practical computer programming experience - jump in. Use your knowledge to guide these tools to produce more. Amplify your productivity. This is the new paradigm. It is not a fad. It works too well.  ( 6 min )

Hey everyone, I've been running ezyZip (a file compression site) for a while, and users kept asking for a way to share large files without the hassle of cloud storage. So I built a P2P transfer feature that works differently from WeTransfer and similar services. Drag and drop your files onto ezyZip File Transfer app Get a link like ezy.zip/ABCDE Your files transfer directly from your browser to the recipient's browser Cloudflare handles the WebRTC signaling to connect you - the actual files never touch any server The technical bit: It's quite simple: Just static HTML/JS files using WebRTC for peer-to-peer connections. Cloudflare handles the signaling server part to establish connections between browsers. Files get compressed into a ZIP on the fly, then stream directly to whoever has your link. Since there's no server storage, there's no file size limit except your patience and bandwidth. Privacy - Files never sit on someone else's server Speed - Direct transfer is often faster than upload then download No infrastructure costs - It's just static files plus Cloudflare for signaling Free - Minimal costs means I can keep it free without limits (There is a 1gb limit just because it needs to hold all the file data in memory) You do need to keep your browser tab open while the other person downloads. But you get live progress updates, and once they're done, the link's ready for the next person. Should work with modern browsers (tested on Chrome) Try it out: https://www.ezyzip.com/share-files-en.html  ( 6 min )

There was a phase when I was on the bench—waiting for a project, learning things on my own, and honestly, a little low. Then one day, my old manager called me up and gave me a task: 👉 “Can you install Zabbix on a Linux server?” Now here’s the funny part. I didn’t even catch the word properly. I heard it as “Jepix” or “Jebix”. 😅 I thought, “What on earth is this tool? Some new tech buzzword?” Finally, I pinged him again to confirm, and he replied: “It’s Zabbix.” That was the first time I ever heard the name.

When I first set up Istio on Amazon EKS, I thought DNS automation would be the easy part. Just install ExternalDNS, connect it to Route 53, and boom — api.yourdomain.com and grafana.yourdomain.com should resolve to my cluster. Most of it did work smoothly. The EKS add-on installed fine, IAM permissions were clear from the docs, and Route 53 was wired up. But there was one thing missing in the documentation that cost me a lot of time: how to make ExternalDNS notice Istio hostnames.

Node.js is single-threaded, meaning it executes JavaScript code in sequence on a single main thread. Yet, it’s famous for handling thousands of concurrent operations without slowing down. The secret behind this magic? The Event Loop, the core mechanism that lets Node.js handle asynchronous operations (like network requests, file system reads, or timers) without blocking the main thread. The Event Loop is at the heart of Node.js’s asynchronous programming model. Understanding how it works and how callbacks, promises, and async/await fit into it gives you the power to write faster, more predictable, and bug-free asynchronous code. Without this understanding, you risk introducing hard-to-debug race conditions, blocking the thread, or misusing async patterns. Imagine a small restaurant with o…  ( 9 min )

Introduction Not so long ago, I had the idea to turn blog posts into podcast episodes. My first few attempts at this resulted in a manual workflow where the final results would be uploaded to YouTube. The flow was as follows: Copy the link to the article from the browser. Paste the link into NotebookLM. Wait for the audio to be generated. See if it was good. Otherwise, tweak the settings and repeat step 3. Once the audio was good, download it to my laptop. Next, use Headliner to create a video from the audio and upload it to YouTube. Needless to say, there was a lot of waiting involved in this process. After doing this a couple times, I thought it would be interesting to try and automate it in some way. In this post, I’ll walk through building podcast-it — a Cloudflare Worker that can ta…  ( 11 min )

Ever since 2020, remote workers have become more common, and we usually work as contractors, which involves invoicing our "customers" on a monthly basis. Every month, we send the exact same invoices to the exact same people, over and over... A few days ago, my boss said something like "please remember to send your invoices, and if you haven't automated it yet, why haven't you?" and I was like "yeah, why haven't I?". So I did: https://github.com/sanbotto/auto-invoice I've set up an automated way to send my invoices on a monthly basis while paying $0. No charges for hosting nor email API, thanks to these services: Cloudflare Workers for the automated script. MailPace for the email API. Anyone who knows me knows that I love Cloudflare Workers and it's mainly because of this, because they have a more-than-generous free tier for you to set up anything you can think of, without having to worry about high bills. When it came to picking an email provider, I did a bit of research trying to find privacy-focused email providers that also had a free tier. I didn't wanna just hook up to any email provider that was gonna start selling my data to 3rd parties or anything like that as soon as I signed up... I noticed several people talking about MailPace, so I reached out to them to ask for access to their free tier and they were kind enough to give it to me (they might do that for everyone who asks, but still). I hope this simple tool can help out someone else stay on top of their invoicing. Catch you on the flippity flip 🏀  ( 6 min )

There was a time when Django was the go-to for web apps. Clean admin, fast MVPs, and battle-tested security—all baked in. It was everywhere. Then came the React hype cycle.

And outside Silicon Valley, governments, universities, and healthcare systems never stopped trusting it. Now in 2025, teams are realizing: speed, security, and stability still matter. Django never stopped delivering. This isn’t nostalgia. It’s about why Django’s back in the spotlight—not because it’s trendy, but because it works.

MCP/Tools Are Not REST API: Here's a Better Design Peter Mbanugo ・ Aug 16 #ai #llm #systemdesign #node  ( 5 min )

Large language models (LLM) without access to current data are almost useless. They need enough data and context to do the right thing, and that's where tool calling becomes leverage. The rise of MCP has unlocked more possibilities for AI agents to access current information and therefore provide useful results. Tools are functions or APIs that models or agents can call to perform tasks. A good practice for tool design is to provide a clear description of what each tool does and when to use it. You’ll find this info in some good resources about tools and function calling, but I’d like to address something else: Tools are not REST APIs. What do I mean? A lot of companies now offer MCP for their products and services. Most of the time, it's just a direct abstraction of their REST or GraphQL …  ( 8 min )

Git Flow is a proven framework, but unlike Git itself, it's not a set standard. Just because it's well-documented and has excellent tool support doesn't mean other git branching techniques couldn't improve your performance much better – Git Flow could cost more than you think. I've implemented Git Flow in teams multiple times, and in all cases it was an improvement. But when things change, the tools have to change sometimes too. The pattern is clear: teams often choose Git Flow because it sounds professional, not because they analysed whether it solves their actual problems. Here's how to choose more intentionally based on my experience.

🌌 The Conclave of All Roads — The Floyd-Warshall Chronicles "In the Age of a Thousand Paths, no traveler could truly know the shortest road until every rumor was tested against every road, from every land to every land." Annals of the Great Cartographer The world was vast — n kingdoms scattered across valleys, mountains, and rivers. fragmented tales of roads: "From my town to yours, it takes 5 days." "I heard that through the mountain pass via K, it might be faster." But no one truly knew the best way to travel from every kingdom to every other kingdom. So the High Conclave of the Great Mapmakers convened to settle the matter once and for all.

Servus and welcome to Day 40 of my journey — today I managed to build the first email automation for the project. The automation is up and running! It feels good to see the system slowly coming together piece by piece. That’s all I could finish today. I’ve been working 11 hours straight for the third day in a row, and on top of that, the heat makes it even tougher to stay fully focused. Still, every bit of progress counts. 🚀 Tomorrow I’ll continue improving the automations and hopefully wrap up this part of the setup. See you tomorrow, Jonathan (0xj0n1)  ( 5 min )

🚀 What I Learned About Software Documentation 📚 I've been studying software documentation practices and wanted to share a structured view that helped me make sense of things. Product documentation 🛠️ focuses on features, expected behavior, and how components fit together. Process documentation 🗂️ focuses on work: who does what, when, and how to ensure consistent, quality outcomes. Produced during SDLC planning Communicates expected features & acceptance criteria Artifacts: SRS, system requirements, user acceptance specs Created by architects/engineers Explains how requirements will be built (conceptual & technical) In-code comments, READMEs, architectural notes Helps current & future devs understand the codebase Test plans, cases, data, strategies, traceability matrices Guides testing & measures quality Manuals, help articles, guides for end users Provide guardrails for consistent, quality execution SOPs = actionable, step-by-step instructions for recurring complex tasks (e.g., release checklists, code check-in, incident response) Formats: flowcharts, hierarchical checklists, step lists Documentation is an investment: ⏱️ Reduced onboarding time 🐞 Fewer bugs from misaligned assumptions 🔁 Repeatable releases 🤝 Better cross-functional collaboration If you’re looking to improve documentation at your org, start with: Who consumes the doc? What decision does it support? How do you keep it maintained? 🤔 What documentation practice has had the biggest impact on your team?

Day 26 is all about stepping up from Freestyle Projects to Jenkins Pipelines, which is the real deal in CI/CD. Let me walk you through it step by step: Pipeline: This is a powerful concept in continuous integration and continuous delivery (CI/CD). Think of it like an automated assembly line for your software. Each step—like building the code, running tests, and deploying the app—is a station on the line, and the pipeline ensures they all happen in the correct order, every time. Declarative Pipeline: This is the modern, recommended way to write a Jenkinsfile. It uses a structured syntax that's easy to read and understand, and it gives you a lot of built-in features. It’s like using a pre-defined template for your pipeline; you just fill in the blanks, which makes the code more maintainable.…  ( 7 min )

When we talk about viruses, most people think of pandemics that attack humans. But what if the next outbreak didn’t target us, but instead our digital infrastructure? Imagine malware that doesn’t just execute a script but rewrites and evolves itself. That’s the terrifying reality AI-powered malware could bring. Traditional malware was dangerous, but at least predictable. Security researchers could dissect it, identify weaknesses, and patch systems. But with machine learning and AI, malware can become adaptive. It can study its own failures, rewrite its attack strategy, and evolve beyond detection systems. Essentially, it turns into a hacker that never sleeps, never eats, and constantly improves. Past attacks like WannaCry or Stuxnet shook the world. AI-powered malware could make th…  ( 6 min )

We had faced this issue in our AWS EKS cluster; I wrote an article about that incident. See it here. CIDR Conflict When Moving from AWS CNI to Cilium TL;DR This entire debugging experience reminded us how low-level networking issues can surface in unexpected ways sometimes months after a change is made. If you’re using Cilium in a cloud environment like EKS: Always define non-overlapping IP ranges for Cilium’s IPAM. Be cautious with large CIDRs like 10.0.0.0/8. Use tools like Hubble and Wireshark in combination to debug packet flows. Document your VPC-wide CIDR usage especially when you use multiple clusters or peered networks. Hope this post helps you avoid days of frustration and maybe even saves your cluster someday.  ( 5 min )

Hey fellow developers! 👋 Remember that gut-wrenching feeling before a technical interview? The sweaty palms, the racing thoughts, wondering if you'll blank out when asked to implement a binary tree? Yeah, I've been there too. That's exactly why I built the AI Interview Simulation feature for Go Interview Practice – and honestly, it's been a game-changer for so many developers (myself included!). Let's be honest – coding interviews are nerve-wracking. You might be a brilliant developer who ships features daily, but put you in front of a whiteboard (or shared screen) with a stranger watching your every keystroke, and suddenly your brain turns to mush. I realized this when I was helping a friend prepare for their dream job at a Go-heavy startup. They knew the language inside and out, had bui…  ( 8 min )

Introduction The CAP theorem is a cornerstone of distributed systems theory, frequently discussed in technical interviews for roles involving system design. Proposed by Eric Brewer, it states that a distributed system can only guarantee two out of three properties: Consistency, Availability, and Partition Tolerance. This trade-off shapes the design of modern systems like databases, microservices, and cloud architectures. In interviews, CAP theorem questions test your ability to reason about distributed system trade-offs and design systems that align with business requirements. Let’s dive into the theorem, its implications, and how to tackle it in interviews. The CAP theorem applies to distributed systems, where data is spread across multiple nodes (servers) that communicate over a netwo…  ( 7 min )

If you’ve been following my Laravel writing journey, you know where we started. 1. Laravel CRUD Like a Pro introduced the idea of a handle() method inside FormRequest classes — a simple way to collapse validation, authorization, and persistence into one clear action. 2.

Senior C#/.NET Developer Learning Plan Topics - C# 10-12 Features Global Using Directives *Explanation *- This feature allows you to declare common namespaces globally, eliminating the need to add using statements in every file. Real-world use: In large projects, many files might use the same set of namespaces (e.g., System, System.Collections.Generic, System.Linq). Global usings can significantly reduce the boilerplate code at the top of each file, making code cleaner and more readable. Code Samples. global using System; global using System.Collections.Generic; global using System.Linq; public class Product { public string Name { get; set; } public decimal Price { get; set; } } public class Order { public List Products { get; set; } = new(); public decimal TotalPrice => Products.Sum(p => p.Price); public void AddProduct(Product product) { Products.Add(product); } public void RemoveProduct(Product product) { Products.Remove(product); } public void ClearProducts() { Products.Clear(); } public override string ToString() { return $"Order with {Products.Count} products, Total Price: {TotalPrice:C}"; } } public class Program { public static void Main(string[] args) { Order order = new(); order.AddProduct(new Product { Name = "Apple", Price = 1.20m }); order.AddProduct(new Product { Name = "Banana", Price = 0.80m }); Console.WriteLine(order.ToString()); } }  ( 5 min )

When I started my career as a developer, one of my senior team members used to construct queries in core PHP using concatenation based on different parameters. Once the construction was complete, he would echo it for different use cases and run it in PHPMyAdmin or SQLyog. Once satisfied, he’d move on. I always liked the way he built those queries. Later, when I moved on to CodeIgniter and eventually Laravel, I noticed something: Developers often write SQL or ORM-based queries buried deep inside controllers, services, views, event listeners — even helpers. This scattered approach leads to redundancy and painful maintenance. We’ve all seen this. This always bugged me. Why repeat the same logic scattered across the application when it can be centralized?  Being an OOP geek, I finally settled …  ( 9 min )

The invention of the internet can be traced back to the 1960s, when researchers, government officials, and other operational heads needed to share information with one another. However, the Internet phenomenon began in the 1990s, when renowned Tim Berners-Lee introduced the "World Wide Web" in 1989. His work was closed during that time, but it was made available to the general public in 1993, and it has since progressed to where we are today. His primary focus was on the inefficient management of files and information at his organization CERN. So he suggested a linked system of information nodes.

MCP (Model Context Protocol) is designed for stateless tool execution, meaning each tool invocation is independent of any previous calls. But many real-world agent workflows need memory or context the ability to remember facts between calls or share state across steps. This article explores how to design MCP-based tools that maintain context across calls, while honoring MCP's stateless and serverless nature. We’ll look at strategies like token passing, external memory stores, chained planning, and best practices from recent research and tooling. MCP was created as a standardized, stateless protocol for interacting with AI tools. It avoids maintaining tool-specific memory across calls, simplifying scalability and inter-service consistency. Each tool invocation receives a payload, executes, …  ( 8 min )

Building Production RAG in 2024: Lessons from 50+ Deployments Retrieval Augmented Generation (RAG) has become one of the most practical ways to make large language models reliable. After building more than fifty RAG systems in production, I want to share what consistently works and what doesn’t. FastAPI over Flask. Async support makes a big difference once you scale. FAISS over ChromaDB, at least for workloads under one million documents. MiniLM over Ada-002. The balance of cost and performance is hard to beat. Many teams ignore this, but it is a small tweak with a big impact on retrieval quality. By normalizing embeddings, you ensure the cosine similarity is consistent. embeddings = embeddings / np.linalg.norm(embeddings, axis=1, keepdims=True) Without normalization, dense vectors with…  ( 6 min )

When your JavaScript bundle is bloated, users pay the price with slow load times, janky interactions, and higher bounce rates. In this post, I’ll walk you through the exact steps I’ve used in production to shrink bundle size and speed up apps. 1. Use Dynamic Imports Avoid loading heavy components or libraries upfront. import dynamic from "next/dynamic"; const Chart = dynamic(() => import("../components/Chart"), { ssr: false }); export default function Dashboard() { return ; } ✅ Result: Loads only when needed, reducing initial bundle size. 2. Tree Shake Your Code Only import what you need. ❌ Bad: import _ from "lodash"; ✅ Good: import debounce from "lodash/debounce"; 3. Bundle Analyzer Use @next/bundle-analyzer to visualize what’s in your bundle. npm install @next/bundle-analyzer In next.config.js: const withBundleAnalyzer = require("@next/bundle-analyzer")({ enabled: process.env.ANALYZE === "true", }); module.exports = withBundleAnalyzer({}); Run: ANALYZE=true npm run build 4. Remove Unused Dependencies Audit your project: npm prune npm dedupe If a package isn’t being used — uninstall it. 5. Optimize Images and Fonts Use next/image for optimized images. Use next/font for font subsets — avoids downloading unused glyphs. 6. Code Splitting Routes Next.js automatically code-splits per page, but you can: Split very large pages into smaller ones. Move rarely used components to dynamically loaded chunks. Key Takeaways Analyze → Optimize → Monitor. Bundle size is a continuous process, not a one-time fix. Your users will thank you with lower bounce rates and higher engagement. Have you checked your Next.js bundle size recently? #nextjs #javascript #webperformance #frontend #reactjs  ( 7 min )

Collections are a fundamental part of any application that manages data. In C#, you have two primary options for working with collections: generic and non-generic.  Collections are classes used to store, manage, and manipulate groups of related objects. Generic Collections Non-Generic Collections Type-Safe by Design No accidental data type mismatches No need for casting Better Performance Common Generic Collections List names = new List(); Dictionary studentMap = new Dictionary(); Queue prices = new Queue(); HashSet uniqueIds = new HashSet(); Object-Based Storage Runtime errors if the cast is incorrect Lower performance due to boxing/unboxing Common Non-Generic Collections ArrayList items = new ArrayList(); items.Add(42); items.Add("hello"); // Works, but can cause issues later Hashtable map = new Hashtable(); map["id"] = 1; map["name"] = "Alice"; When you work with large amounts of data, the cost of boxing/unboxing and casting becomes significant. ArrayList list = new ArrayList(); // Value type is boxed list.Add(1); // Unboxed and cast manually int number = (int)list[0]; VS List list = new List(); // No boxing required list.Add(1); // Clean and safe int number = list[0]; These are benchmarking result of adding, and iterate throw elements for both type of collections. Generic collections are the default choice for modern .NET development providing type safety, clarity, and performance. Non-generic collections still exist for backward compatibility but are largely obsolete for most use cases. Choose wisely and your application will thank you with fewer bugs and better performance.  ( 6 min )

Basic Struct of smart contract Pragma version declaration Each Solidity source file should begin with a pragma statement. It specifies the compatible compiler version range. It helps prevent potential errors or vulnerabilities. For example: pragma solidity >=0.7.0 =0.7.0 <0.9.0; contract HelloWorld { uint256 number; function store(uint256 num) public { number = num; } function get() public view returns (uint256) { return number; } } This is a simple HelloWorld contract demonstrating state variable storage and retrieval. After deployment, the contract instance appears in the 'Deployed Contract' area. You can input parameters to call the store function, which modifies the blockchain state and also you can click the get function to read the current state value, which is a read-only operation.  ( 5 min )

What is MCP? Model Context Protocol (MCP) is the hottest topic in AI world right now! Because it solves a major limitation of the LLMs. LLMs has limited knowledge based on the data on which it was training. It doesn't have any idea about the changes happened in the world after it's training cut-off. To solve this problem, we need external tools to give additional information to LLMs. And depending on the judgement of the LLM, it should be able to call these tools whenever required, and the tool will pass the information back to LLM (by calling an external API or so). And you can consider MCP as the standardised way to build these external tools. The simplest analogy is if your laptop is an LLM, then USB connector the MCP and the different USB drivers you plugin through this connector are…  ( 7 min )

A Personal Note Before We Begin When I was in college, I had no support from my college. I was unprepared, unaware, and honestly… just trying to survive.

Hi everyone, react-kanban-kit, an open-source Kanban board package I’ve been working on! If you’ve ever needed a Kanban-style task board in your React project, you know how tricky it can be to balance simplicity, customization, and performance. That’s exactly why I built react-kanban-kit. ✅ Lightweight and easy to integrate npm install react-kanban-kit import { Kanban } from "react-kanban-kit"; const MyKanbanBoard = () => { const dataSource = { root: { id: "root", title: "Root", children: ["col-1", "col-2", "col-3"], totalChildrenCount: 3, parentId: null, }, "col-1": { id: "col-1", title: "To Do", children: ["task-1", "task-2"], totalChildrenCount: 2, parentId: "root", }, "col-2": { id: "col-2", …  ( 6 min )

Preface Remix is a very popular IDE, which is designed for smart contract development using Solidity. It simplifies the process of coding, compiling, deploying and testing. Online IDE:: No installation is required, Files are stored in the browser local storage, which may result data loss. the important files need to manual download and backup. Desktop Application: It is recommended to use this version, because it stores files and workspaces in your computer disk. File Explorer: It allows you to browse and mange files. Workspaces: Workspaces serve as the core concept for organzing project, like a project folder. You can create, rename and delete it. Solidity Compiler: Source code must be compiled into byte code before deployment. 4.Settings: you can select the compiler version, pragma statement specifies compatible versions. Remix VM: It provides a local, temporary blockchain environment. Injected provider(MetaMask): Connect to MetaMask to deploy contracts to the mainnet or testnet After compilation, select the contract and click 'Deploy' Once deployed, contract instances apper and functions can be called you can activate or deactivate plugins to extend IDE functionality.

There’s a new term floating around in the tech world: "vibe coding." It sounds cool, right? It’s the idea that you can just "feel out" what you want an AI to do, type a quick prompt, and a few seconds later, you have a working block of code. For junior developers and aspiring coders, this seems like a dream come true. You can build an app without ever truly learning how the pieces fit together. But here’s the harsh reality: this shortcut is a career death trap. The problem isn't the AI itself. AI is an incredible tool, and seasoned developers are using it to become even more efficient. The problem is the "vibe" part—the reliance on magic over understanding. It’s like using a powerful calculator to solve a math problem without ever learning what addition or multiplication actually means. Yo…  ( 7 min )

Introduction In modern web apps, debouncing is a powerful feature—especially when dealing with frequent user input, such as search bars, form validation, or filtering data. If you’re preparing for React interviews, one common question you'll face is: "How do you implement a useDebounce hook in React?" In this blog, we’ll build a useDebounce custom hook from scratch, explore why it's useful, and show how you can integrate it into real-world projects. Debouncing ensures that a function is only executed after a certain delay and only if no new event has occurred in the meantime. It’s especially useful for: Search input fields API calls during typing The useDebounce Hook Let’s dive right into the code: import { useEffect, useState } from 'react'; const useDebounce = (value, d…  ( 7 min )

Recently I was working on a project to backup files via the Autodesk BIM360/Construction Cloud API. My initial prototype took 12 hours to backup roughly 100 GB (40,230 files in 11,737 folders) which wasn't good. Due to the fast pace data is being added to the account, within 1–2 years the backup would be taking over 24 hours. After a program re-write which included moving the file downloading logic from a synchronous foreach loop to a Parallel.ForEachAsync loop I was able to get the nightly backup time down to 3 hours. Benchmark.NET. The first was on a small project containing 300 MB (136 files in 30 folders): BenchmarkDotNet=v0.13.1, OS=Windows 10.0.19044.1645 (21H2) Intel Core i7-5820K CPU 3.30GHz (Broadwell), 1 CPU, 12 logical and 6 physical cores .NET SDK=6.0.202 [Host] : .NET 6.0.…  ( 7 min )

Alright, so I was grinding some LeetCode problems (as one does) and in one of a problem I saw this pattern—Double Ended Queue or Deque (pronounced "deck," not "dee-queue," learned that the hard way 😅). At first, I was like, "Why not just use a normal queue or a stack?" But turns out, deques are game changer for certain problems. So, let’s break it down—what it is, how to implement it (in TypeScript, you can use your fav language), and where it uses in DSA. A Deque is like a queue, but with some more powers. In a normal queue, you can only add to the back (enqueue) and remove from the front (dequeue). But a deque lets you add/remove from both ends. Think of it as a hybrid between a stack (LIFO) and a queue (FIFO). pushFront(x): Add x to the front. pushBack(x): Add x to the back. popFront()…  ( 8 min )

Hi everyone 👋 I built a new addon for Storybook called Range Controls. It lets you adjust story args (strings, numbers, and arrays) with sliders — making it easier to stress-test layouts and catch edge cases. I often used Storybook’s built-in argTypes with type: "range" sliders to check design variations. That works great for primitives (strings, numbers), but for more complex structures — like arrays of nested objects (e.g. tags inside a card) — I found myself writing the same boilerplate code again and again. This addon was created to reduce that overhead and make it simpler to configure sliders for strings, numbers, and arrays. Card List Range Controls Panel 👉 Live Demo: Chromatic preview npm install --save-dev storybook-addon-range-controls .storybook/main.js addons: [ "@storybook/addon-docs", "storybook-addon-range-controls", ]; parameters: { range: { title: { type: "string", min: 0, max: 50, step: 5 }, likes: { type: "number", min: 0, max: 999 }, tags: { type: "array", min: 0, max: 5, items: { type: "string" }, defaultItem: (i: number) => `tag-${i + 1}`, }, } } I’d love to hear your thoughts: Is the API design clear enough?

When building or testing streaming-related applications, developers often need a quick way to sideload apps onto Fire TV Stick or Android TV devices. Traditionally, this requires transferring APK files manually, configuring ADB, or using external storage — all of which can be time-consuming. This is where the Downloader codes list comes into play. By using a Downloader code, developers can share or access apps in seconds, without having to juggle complex deployment steps. A Downloader code is essentially a short numeric identifier used with the popular Downloader app (available on Fire TV and Android TV). Instead of typing long URLs or uploading APKs, you just enter the code, and the Downloader app fetches the file directly. For example, instead of pasting a long URL like: _https://example…  ( 6 min )

This post is about how to perform Threat Modelling using the STRIDE model. I'll also highlight some tips with using OWASP Threat Dragon, and some practices I choose to follow. Threat modelling is a critical part of a secure development lifecycle. We use a model, such as STRIDE, to help us identify, review and mitigate potential threats and vulnerabilities within a software system (or application). The goal is to identify and mitigate threats early, before they become problems. It is critical that everyone in the team responsible for the software application is involved, as everyone can bring a different perspective. Furthermore, it helps educate all members of the team, as application security is everyone's responsibility. STRIDE is a threat classification model which was developed by Micr…  ( 10 min )

It’s been an exciting first week in my cloud journey. While I’ve had some past experience with Linux and basic scripting, it’s been a while since I last explored the cloud. So, I dedicated this week to revisiting the fundamentals and bridging the gap between my existing skills and the next phase of my learning. I started by moving around directories, installing software, and managing files. I first learned about package management — a tool to find software from repositories, install it, update it, and remove it. Package management taught me that every distribution has its own way of handling software, but the core principle remains same. Then came process management. At first, “killing” a process was confusing because I had to read about signals and what they actually did. But I soon reali…  ( 6 min )

Writing clear and consistent pull request (PR) descriptions is… let’s be honest — a chore. But what if your PR titles and descriptions could write themselves — tailored, professional, and markdown-formatted? That’s exactly why I built GitHub PR-Scribe-AI ✨. 🧠 What It Does 🔹 Generates high-quality PR titles + descriptions automatically. 🔹 Uses AI models of your choice → OpenAI GPT or Google Gemini. 🔹 Produces markdown-ready summaries from your code diff. 🔹 Lets you inject custom fields (e.g., “Risk Level”, “Jira Ticket”, “Reviewer Notes”) into every PR. 🔹 Keeps your API keys 100% local — no data is sent to me or third parties. Basically, it’s your AI co-pilot for pull requests. 🎯 Why I Built It As a developer, I wanted: Faster reviews → reviewers spend less time guessing what my code does. Consistency → all PRs follow a professional, structured format. Choice → not being locked into just GPT or just Gemini. None of the existing extensions gave me flexibility + privacy. So, I scratched my own itch. ⚡ Quick Demo Install the extension → GitHub PR-Scribe-AI Connect your OpenAI or Gemini API key Open a PR on GitHub [on Compare page] Click “Generate” → Watch the title + description appear automagically ✨ Yes, it even formats it in markdown so your PR looks like this: ## Summary This PR refactors the user authentication flow to improve readability and reduce API calls. ## Changes - Replaced nested callbacks with async/await - Extracted reusable token validation logic - Added unit tests for edge cases ## Risk Low – No breaking changes for existing API consumers. 🔒 Privacy First No data leaves your browser. 🚀 What’s Next I’m actively shipping new features, including: 🔗 Try It Out 👉 Install GitHub PR-Scribe-AI on Chrome now. I’d love your feedback — if you’re a developer who reviews PRs daily, this tool was built for you.

Setup APIs are connections between computers to exchange information or data. For a website, we expect them to return a visual change, something as simple as a now different text or a floating message in the corner of the screen. However, what if the API we are waiting for is taking too long to respond to us? Are we supposed to stare at the screen now? Is there anything else we can do on the website at the moment? Such frustration and panic would ruin the experience of any patient user. And to us developers, the general solution is an API that would return its progress periodically. In this tutorial, I’m going to introduce an answer to the above issue, by using EventSource class along with a Flask API server.

JavaScript’s Map is often overshadowed by Object, but for many key–value use cases it’s the better tool—faster, safer, and more flexible. This article walks through what a Map is, how it works under the hood (hashing, buckets, collisions), why operations are usually O(1), when they’re not, and when to choose Map over Object. Map? In simple terms: Map is a key–value data structure (a hash table). Unlike plain objects, Map allows any type of key (strings, numbers, objects, functions) and gives predictable iteration, a built-in size, and methods tailored for dictionary behavior. // ❌ Common mistake: Using Object like a Map let players = { USER_1: { name: 'Shubham', score: 120 }, }; // This will throw: players.set is not a function players.set('USER_2', { name: 'Atharva', score: 200 }); …  ( 8 min )

Introduction Lately I’ve been looking into hosting open‑source models on dedicated Azure virtual machines and thought: how hard can it be to pick the right VM and how much cost can you actually save by choosing a smaller model? Of course, Microsoft’s serverless options are cheaper and much easier to deploy. But I like to know how things work and to manage my own compute, partly out of technical curiosity, partly for compliance and privacy. Running on dedicated VMs gives you more control on both fronts. I couldn’t find a clear, practical guide for sizing a VM based on the model you choose, so I built one: a quick single page web app. Try it here → Live Azure LLM Sizer (code: GitHub).

This article outlines the comprehensive steps taken to secure Apache's port, including the reasoning behind each action, and provides a clear guide for future maintenance. Why the Firewall Was Necessary Previously, Apache's port 3004 was left open for all incoming connections, which posed a significant security vulnerability. An open port is an entry point, making the system susceptible to various attacks, including unauthorized access attempts, port scanning, and Denial-of-Service (DoS) attacks.

Most Web2 developers dip into Web3 thinking it’s just another backend with a different API. Then they hit gas fees, strange error messages, and a completely alien account system.

In addition to simply adding sudo where necessary, it can correct typos in commands, add missing flags, and much more. However, I found two drawbacks. First, the program is written in Python, which can make it slow. Second, it has not been supported for a long time, so it does not work on newer versions of the language.

Today I ran into something funny — I needed a decent HTML report for my pytest run, and my first thought was: Usually, that means: Installing pytest-html or allure-pytest Setting up .ini or passing a long list of CLI flags (or even installing Java in allure’s case) Making sure people on other machines can actually open the report Writing a little conftest.py hook to add metadata Trying not to break CI/CD in the process Time spent? Way too much, just for a simple report. And in my case, there was another catch — I was running tests in parallel with pytest-xdist. If you’ve done that before, you will need another merger plugin to merge all the xmls So I looked around for that plugin but found pytest-html-plus. I didn’t even read the docs at first — I just installed it: pip install pytest-html-plus Done. That’s it. What surprised me: It handled parallel runs without breaking the report (even with xdist) Added metadata like branch, commit, environment, and timestamp automatically I could copy logs and errors with one click The report was shareable as-is without worrying about dependencies I didn’t have to touch a single test file — no extra hooks or decorators Honestly, the whole “report” part of my workflow went from “ugh, I’ll do it later” to “done in 5 seconds”, even in CI. If you’ve been wrestling with HTML reports in pytest — especially with parallel runs — this was a nice surprise.

Developing modern web applications often means working with features that require a secure context. Your browser, third-party APIs, and security best practices all push you towards using HTTPS, even in your local development environment. In this comprehensive guide, we'll explore why you need localhost HTTPS, walk through the traditional methods of setting it up and demonstrate and easy way to set it up using Tunnelmole, a powerful, one-command solution to get a secure, shareable HTTPS URL for your local server quickly. Running your local server over HTTPS (Hypertext Transfer Protocol Secure) is no longer a "nice-to-have"; it's often a necessity for several reasons: Browser Feature Requirements: Many modern browser APIs will only function in a "secure context". If you try to use them over…  ( 10 min )

🤖 What is Generative AI? Generative AI (Gen AI) is a type of artificial intelligence that can create new content like: Text (e.g., writing emails, summaries, answers) Images (e.g., AI-generated art) Code (e.g., coding assistants like GitHub Copilot) Music, videos, and more 🎯 In simple words: You give the AI a prompt (a message or question), and it gives you a new response or result. Here’s a basic process: The AI is trained using massive datasets (books, articles, code, images). It learns patterns, language, and structure. You give it a prompt like “Explain gravity,” and it uses its knowledge to give a relevant answer. It predicts the most likely next word/token — one at a time — to form a complete response. A token is a small piece of text — a word or part of a word. AI doesn’t unders…  ( 9 min )

When building complex React applications, we often deal with multiple instances of similar pieces of state. Managing each one separately with individual atoms can quickly become messy and repetitive. Recoil provides a powerful utility called atomFamily to solve this problem. In this article, we’ll break down what atomFamily is, why it’s useful, and how it works in the context of a Todo app. atomFamily? atomFamily is a factory function that allows us to create parameterized atoms. Instead of writing separate atoms for each todo, we can create one family of atoms. Each atom inside the family is uniquely identified by its parameter (like an id). This makes managing dynamic state instances (e.g., multiple todos, users, or chat rooms) simple and scalable. Let’s break down your provided exampl…  ( 6 min )

Definition: What is Over-Engineering? Over-engineering in software and systems development occurs when a solution is made more complex than necessary to meet its current requirements. It often involves building features “just in case,” designing for hypothetical scalability, or adding abstraction layers that serve no immediate purpose. Unlike necessary complexity—which arises naturally when solving hard, real-world problems—over-engineering is avoidable complexity. It doesn’t improve the product’s core value but instead increases its burden. In short: necessary complexity solves real problems; over-engineering solves imagined ones. Several recurring factors push teams toward this trap: Developers optimize performance or scalability far beyond what is needed. As Donald Knuth famously said…  ( 7 min )

WTF is this: Confidential Computing "Confidential what-now?" Yeah, I felt the same way when I first stumbled upon this term. It sounds like something out of a spy novel, doesn't it? But fear not, dear reader, for today we're going to demystify this tech buzzword and make it ridiculously easy to understand. What is Confidential Computing? Imagine you're at a coffee shop, and you need to send a super-secret document to your colleague. You wouldn't just leave it on the table for anyone to see, would you? You'd probably encrypt it, or use a secure channel to send it. That's basically what Confidential Computing is, but for computers. It's a technology that allows sensitive data to be processed and analyzed while keeping it encrypted and protected from unauthorized access. Think of it like a di…  ( 7 min )

Ever wanted to host your apps running on localhost straight to the internet? Be careful—now you won’t be able to say “it works on my local”.

Introduction: From Localhost to the World As a developer, your local machine is your sanctuary. You build, test, and iterate on applications using a localhost server, a private loopback address (like 127.0.0.1) that lets you see your work in action without needing an internet connection. This setup is fast, secure, and perfect for the initial stages of development. But what happens when you need to break out of this local bubble? You need to test a webhook integration from a third-party service like Stripe, Shopify, or Slack, which can only send requests to a public URL. You want to show a client or a colleague a work-in-progress without deploying it to a staging server. You need to test your web app on a real mobile device, not just a browser emulator. You are collaborating with a front…  ( 10 min )

If you’ve been messing around with Docker for a while, chances are your system has turned into a junkyard of old containers, images, and volumes you don’t even remember creating. Docker is amazing, but it’s also a hoarder by default. And let’s be honest. if you’re using Docker Desktop, especially on Mac or Windows, that bloated piece of software is probably eating your RAM for breakfast. My honest advice: uninstall Docker Desktop. On Mac/Linux and you still want a GUI? → Check out OrbStack. Way lighter, way faster. Or, better yet: learn the CLI like a seasoned dev. Once you get comfortable, it feels way cleaner and faster. Now, let’s talk about how to completely clean up Docker. weekly if you’re a heavy Docker user, or at least twice a month to keep things fresh. This will clear out unused containers, images, networks, volumes, and if you want, completely nuke Docker’s system files. The easiest, safest way to clear unused junk: docker system prune -a --volumes -a: removes all unused images (not just dangling ones). --volumes: removes unused volumes too. Think of this as Docker’s version of spring cleaning. (Run this once a week, and Docker won’t ever balloon out of control.) Sometimes you just want a fresh start: docker stop $(docker ps -aq) docker rm $(docker ps -aq) Go full “factory reset” mode on your Docker resources: docker rmi -f $(docker images -aq) docker volume rm $(docker volume ls -q) docker network rm $(docker network ls -q) ⚠️ Warning: this wipes Docker’s entire state, including cached layers. sudo systemctl stop docker sudo rm -rf /var/lib/docker /var/lib/containerd sudo systemctl start docker Keeps things lean and mean. Ditch Docker Desktop → Use OrbStack (Mac) or CLI (Linux). Run docker system prune -a --volumes once a week (or at least twice a month). Reset Docker fully only if things are really broken. Your future self (and your SSD) will thank you.  ( 6 min )

--- Animations have become a core part of modern digital experiences. From websites to mobile apps to games, animation improves usability, brand identity, and user engagement. But when it comes to choosing the right tool, the debate often comes down to Rive vs Lottie. Both are powerful, but which one should you use in 2025? Let’s break it down.

This video by Danny Maude reveals that pro-level ball striking boils down to controlling the low point of your swing arc—specifically your pelvis position at impact. He shares two simple drills (the “yoga wedge” for an early pelvis shift and the “pocket move” for perfect low-point control) that will help you hit your driver straighter, compress your irons, and eliminate fat, thin or slicing shots. You’ll also discover why impact matters more than your backswing, how to fix your swing path, and setup tweaks for more distance and accuracy. With clear timestamps and easy practice drills, you’ll be on the range in no time nailing consistent, powerful strikes. Watch on YouTube  ( 5 min )

Last 2 weeks, I was participating in the ARC AGI 3 preview competition. I was trying out different techniques to solve the problem. The competition challenge is that we need to build an agent to win an unknown game. Most of the things that I tried didn’t work well. My solution uses Text LLM, Image LLM, and Video LLM. But still, it doesn’t perform well enough to win the full game. In the full development, I used Gemini. There were rate limit errors. After a few manual experiments and runs with a random agent, I created the below initial flow: Generate a random trial gameplay and reset the game. Only use the frames that have an effect in analysis. Pass the gameplay video to the LLM, then generate 10 hypotheses out of it (Retrieval) [Analysis].

Every React component has a story. It’s born (when it first appears on the screen), it lives (responding to user input, fetching data, updating the UI), and eventually, it retires (when React says, “Thanks for your service” and removes it from the DOM). This journey is called the component lifecycle — and understanding it isn’t just trivia. It’s the secret to: Fetching data at the right moment (and only once) Avoiding awkward bugs like double API calls or memory leaks Writing components that feel smooth, not sluggish Now, don’t worry — we’re not going back to the class-component days of memorizing things like componentDidMount or componentWillUnmount. Those still exist historically, but we’re in a hooks-first world, so we’ll learn lifecycle concepts and map them to modern function componen…  ( 16 min )

In today’s app-driven world, user experience (UX) is everything.

In just a few lines of code, you can reliably switch users between browsers on both Android and iOS.  ( 6 min )

I spend a lot of time writing. Articles, ideas, updates. But every time I wanted to share something I ran into the same problem. I’d finish a draft, polish it up, then open dev.to. Copy and paste. Fix the formatting. Publish. Then I’d do the same on Medium. Then on Hashnode. Then on Beehiiv. Four tabs. Four logins. Four different formatting tweaks. Four times the work for a single article. After a while, it felt broken. Writing should be about the words, not about fighting platforms. That’s what led me to start building Cross Write. What if there was one place where you could write your article, polish it if needed, and then publish it everywhere? So I started hacking on a tool with a simple flow: Start with a blank page or just an idea Use GPT to help expand, rewrite, or clean up your draft (with your own key) Save it as a draft, or schedule it for later When it’s ready, publish directly to dev.to, Medium, Hashnode, and Beehiiv in one click Instead of repeating the same process across four platforms, you write once and publish everywhere. I decided to make Cross Write free and open source. Two reasons: I know a lot of indie hackers and newsletter writers who deal with the same pain. If the tool helps them, great. I don’t want this locked behind another paid wall. Writers already have enough to worry about with reach, engagement, and growing an audience. The goal is to make writing and publishing simpler, not more complicated. Cross Write is still early, but it works. You can draft, polish, schedule, and push out content to multiple platforms. I’m polishing the UI and testing the integrations now. I’ll be launching it on Product Hunt soon, but I’d love to get early feedback. If this sounds like something you’d use, you can join the waitlist here: 👉 https://crosswrite.validatemy.app  ( 6 min )

How OrKa’s Maternal-Inspired Workflows Echo Geoffrey Hinton’s Call for "Maternal Instinct" in AI. In August 2025, Geoffrey Hinton told the Ai4 conference something that cut through the usual AI safety rhetoric: "If it’s not going to parent me, it’s going to replace me." He explained that AI systems should be designed with what he called maternal instincts. Not human feelings, but structural priorities that lead an AI to protect and nurture its users, even if it becomes vastly more capable than us. It is an unusual metaphor, but the more I thought about it, the more I realized that the orchestration patterns I have been building in OrKa already encode some of these protective behaviors in a way that is concrete and reproducible.

That was the moment I truly understood the gap between building a UI and delivering a flawless user experience. I had crafted a beautiful interface—smooth animations, responsive layouts, pixel-perfect design—but within hours of going live, reports of broken buttons, misaligned components, and unexpected behavior started coming in. It wasn’t the design. It wasn’t the code quality. 🚨 Why Front-End Testing Matters Without it, you’re essentially gambling with your product’s reputation: Bugs slip through unnoticed until users complain.

As I'm listening to it again, I find it rather depressing! I think the main thing I like about this song was the "down-du-down-du-down", and I pretty much the entire song around that section. That's why the refrain is not so bad. That said, for the rest of the lyrics, it was pretty much "whatever rhymes with brown" or something like that. The melody kinda flows well though.

By Frank — Senior Electronics Engineer (USA) If you’ve ever wondered how tiny components on a smartphone or laptop stay firmly attached, the short answer is: controlled heat. Reflow ovens are the workhorses that turn solder paste into strong, reliable joints. Think of a reflow oven like baking a delicate cake. You don’t slam it in at full heat, you preheat, hold, spike, then cool. A reflow oven moves PCBs through a series of zones that gently preheat the board, soak to equalize temperature, spike into the reflow peak to melt solder, and then cool at a controlled rate so joints solidify without stress. The result is consistent surface-mount soldering across the entire board. Preheat zone: The board warms up gradually so moisture and solvents evaporate and components aren’t shocked. Soak zo…  ( 6 min )

When building applications with Recoil, you often need to manage state that looks similar but is distinguished by some dynamic parameter — for example, user profiles, messages, or notifications that are stored individually. Defining a separate atom for each case would be repetitive and inefficient. This is where AtomFamily comes into play. atomFamily is a factory for atoms. Instead of creating multiple atoms manually, you can create a function that generates unique atoms based on a parameter. Each atom created by the family behaves like a normal atom but is identified by the parameter you pass in. This makes it perfect for dynamic data structures where you don’t know beforehand how many atoms you’ll need. import { atomFamily } from "recoil"; const myAtomFamily = atomFamily({ key: "myAto…  ( 6 min )

Learning to code has been both exciting and challenging. I’ve been focusing on JavaScript recently, and I’ll be honest—sometimes it feels overwhelming. But I’ve learned that progress doesn’t happen all at once; it happens step by step, line by line. 💡 Along this journey, here are some tips that help me (and might help you, too): Start small. Don’t wait to master everything before building. Even the simplest project matters. Consistency is key. Coding daily, even a little, compounds into big progress. Break problems down. Big challenges become manageable when split into smaller tasks. Learn in public. Sharing your journey keeps you motivated and inspires others. Focus on growth, not perfection. Every error is just a step toward improvement. ✨ My journey isn’t about being perfect—it’s about being consistent.

Over the last year, you've probably seen a wave of AI tools promising to make code review faster. Platforms like CodeRabbit, CodeAnt, and even GitHub Copilot now step in to provide automated review comments when you open a pull request or merge request.

Traditionally, a senior engineer had to go through each line of code, highlight every issue, and leave detailed comments. That process works -- but it comes with hidden costs. Senior reviewers spend valuable time pointing out mundane issues (styling violations, misplaced braces, redundant loops), while the actual developer waits hours or even days for the first round of feedback.

If you have just started with deep learning, one optimizer you will hear about again and again is the Adam Optimizer. It shows up in tutorials, research papers, and almost every popular machine learning library. So, what makes it special? Adam stands for Adaptive Moment Estimation. In simple terms, it is a smart way to adjust learning rates while training neural networks. Imagine walking downhill to reach the lowest point. Instead of moving blindly, Adam remembers the direction of previous steps and changes its speed, so the path becomes smooth and efficient. Why Developers Use Adam Trains models faster than many traditional optimizers. Works well with noisy or sparse data. Requires very little manual tuning. Built-in support in PyTorch, TensorFlow, and Keras. Key Benefits Faster convergence. Good for computer vision and NLP tasks. Combines the strengths of momentum and RMSProp. Drawbacks Can sometimes settle in less optimal solutions. Consumes more memory since it stores extra parameters. Common Use Cases Image Recognition (CNNs) Natural Language Processing (BERT, GPT models) Reinforcement Learning Forecasting and Time Series Final Thoughts The Adam Optimizer is often the first choice for deep learning projects. For students, developers, and freshers, it is a great starting point to build and train neural networks without too much hassle.  ( 5 min )

When building real-world applications, we often need to connect them with databases to store and retrieve data. In Java, this is achieved using JDBC – Java Database Connectivity. JDBC is a standard Java API that allows applications to connect and interact with relational databases such as MySQL, PostgreSQL, Oracle, or SQL Server. JDBC (Java Database Connectivity) is: A standard Java API for connecting Java applications with relational databases. A set of classes and interfaces provided by the Java platform. Useful for performing CRUD (Create, Read, Update, Delete) operations in databases. To connect a Java program with a database using JDBC, we follow 7 main steps: import java.sql.*; Each database needs a specific driver. Example for MySQL: Class.forName("com.mysql.cj.jdbc.Driver"); We c…  ( 6 min )

Posted on dev.to - August 16, 2025 So, I've been building DApps for about 2.5 years now, and honestly, choosing the right blockchain still gives me analysis paralysis sometimes. Last month I shipped a pretty complex DeFi aggregator on both NEAR and Polygon zkEVM (don't ask why, it seemed like a good idea at the time), and figured I'd share what I learned from actually building on both platforms instead of just reading whitepapers. Spoiler alert: they're both good, but in very different ways. And yes, I'm going to include actual code because I'm tired of blockchain comparisons that never show you what development actually looks like. NEAR: Feels like building modern web apps, predictable costs, human-friendly addresses, but smaller ecosystem Polygon zkEVM: Ethereum compatibility is huge, ma…  ( 13 min )

🌵 Why “Windows Albuquerque”? Albuquerque is not just a city. It was Microsoft’s birthplace, before Redmond. It symbolizes engineering, technical roots, and systems that respected the user. Naming this version after it is not marketing. It’s a historical correction. Windows Albuquerque is not just another release. It’s a return to fundamentals. Solaris Zones were an elegant solution for creating isolated execution environments without heavy virtualization. Each zone shared the system kernel but had its own user space, configuration, and resources. They weren’t virtual machines. They weren’t containers. They were controlled, reversible, and auditable zones. True isolation without duplicating the kernel Granular control over CPU, memory, disk, and network Declarative configuratio…  ( 7 min )

🔹 Problem: 1323. Maximum 69 Number Difficulty: #Easy Tags: #Greedy, #Math You’re given a positive integer made up of only digits 6 and 9. You are allowed to change at most one digit (6 → 9 or 9 → 6). Brute Force Idea: 6 with 9 one by one, compute all possible numbers, and pick the maximum. This works, but it’s wasteful. Optimized Strategy (Greedy): To maximize, we only need to flip the leftmost 6 into 9. Why? Because digits on the left have higher weight in decimal representation. No need to check further, just do a single replacement. Algorithm Used: Greedy + String Manipulation ⚙️ Code Implementation (Python) class Solution: def maximum69Number (self, num: int) -> int: # Convert number to string for easy manipulation num = str(num) # Replace only the first '6' with '9' num = num.replace('6', '9', 1) # Convert back to int and return return int(num) Time: O(n), where n = number of digits (string scan + replacement). Space: O(n) due to string conversion. ✅ Greedy worked because we only need to maximize once at the highest place value. 💡 Learned that string manipulation can often simplify digit-based problems. 💭 Similar problems often involve changing the most significant digit first.

Intro: Hey JS Devs! AI's Calling, and Guess What? You're Already Ready. The hype surrounding Large Language Models (LLMs) like ChatGPT, Gemini, and Claude is not just media fluff; these models are genuinely reshaping industries. The question isn't whether AI will impact your work, but how. And here's a provocative thought: your JavaScript skills are not just relevant, they're a secret weapon. For too long, the AI narrative has been dominated by Pythonistas. But JavaScript's ubiquitous presence, its unmatched flexibility, makes it a compelling choice, perhaps the choice, for crafting AI applications. This isn't about replacing Python in core AI research; it's about leveraging the power of LLMs within the web ecosystem, where JavaScript reigns supreme. Consider this journey an intellectual…  ( 9 min )

When I first heard the term Computer Science, I imagined complex codes, robots, and a world where only “genius” programmers survived. I thought it was something too complicated for someone like me. But as I slowly took my first steps, I realized Computer Science isn’t just about writing code it’s about solving problems, creating things, and shaping the future. Why Computer Science? We live in a time where technology drives almost everything. From the way we shop, connect with friends, travel, or even order food Computer Science is the silent force working behind the scenes. Choosing to learn it isn’t just about building a career; it’s about being part of the change that shapes the modern world.

When working with Google Compute Engine (GCE), you often need to automate tasks like installing software, configuring firewalls, or running custom commands as soon as your VM boots up. This is where Startup Scripts come in. A startup script is a file containing commands that automatically run when a VM instance boots. Supported on both Linux VMs and Windows VMs. Can be configured at VM-level or Project-level. VM-level startup scripts override project-level scripts. 👉 Example use case: If you want all VMs in a project to have the same script applied (like installing antivirus or monitoring agents), you can configure a project-level startup script. Types of Scripts Bash Scripts (most common). Non-Bash Scripts — supported if you specify an interpreter. Example: #! /usr/bin/python3 print("Hello from Python startup script") What Happens Behind the Scenes? When you provide a startup script: Compute Engine copies the script to the VM. It sets run permissions on the script. The script runs as root user when the VM boots. ✅ How many startup scripts can you use per VM? You can configure multiple startup scripts. ✅ Order of Execution Metadata Key: startup-script Scripts provided directly in metadata or locally → run first. Metadata Key: startup-script-url Scripts stored in Cloud Storage (GCS) → run second. ✅ Script Size Limit Maximum allowed size: 256 KB Automatically install software (Apache, Nginx, Databases). Configure monitoring agents and logging tools. Apply project-wide policies without manually configuring each VM. Speed up provisioning by automating boot-time tasks.  ( 6 min )

Hey everyone 👋, As a web developer, I wanted to work on a fun side project that also helps people. Growing up, I always loved the idea of waking up and wondering: “Will school be canceled today because of snow?” So, I decided to turn that nostalgia into a little web app: Snow Day Calculator 🚀. 🌨️ What It Does The tool is super simple: You enter your location ❄️ It checks weather data ☁️ Then it gives you a prediction on the chances of a snow day. It’s completely free, lightweight, and works on both desktop and mobile. ⚙️ How I Built It Frontend: Vanilla HTML, CSS, and JavaScript (no heavy frameworks — I wanted it fast). Hosting: Netlify — great for free deployments. Performance: Optimized for Core Web Vitals (FCP/LCP ~1.7s 🚀). Fun factor: Tried to keep it playful yet useful. 🛠️ Lessons Learned Even small projects benefit a lot from performance optimization — lazy-loading images, reserving space for elements to reduce layout shift, and preloading fonts made a big difference. Building something fun makes it way easier to actually finish the project. Sharing projects like this is a great way to improve as a developer (and get feedback from the community!). 🔗 Try It Out 👉 You can try the app here: Snow Day Calculator Would love feedback, feature requests, or even bug reports. Thinking about adding: Different regions’ school calendars More accurate weather models A little fun animation for snow 🌨️ 💬 Question for the community: What’s a small/fun project you’ve built recently just for the joy of it?  ( 6 min )

Introduction to Document Data Extraction In today’s digital economy, businesses rely heavily on information to make decisions, streamline workflows, and serve customers effectively. Yet much of the data organizations manage still exists in documents such as PDFs, invoices, contracts, reports, and scanned images. Document data extraction refers to the process of pulling meaningful information from these files, whether structured, semi-structured, or completely unstructured, and converting it into formats that can be analyzed, stored, or integrated with other systems. By automating this process, organizations gain speed, accuracy, and the ability to unlock insights hidden in mountains of paperwork. For decades, companies have struggled with manual data entry.

7 Twitter Prompts That Grew My AI Audience Jaideep Parashar ・ Aug 16 #ai #automation #openai #learning  ( 5 min )

En el mundo educativo, la pregunta incómoda es: ¿Se está evaluando lo que el estudiante sabe o solo su capacidad de usar bien la IA? En el mundo del desarrollo de software, la inquietud es parecida: ¿Seguimos entendiendo el código o solo sabemos copiar y pegar lo que la IA nos da? (Nistal, 2025). Lo interesante es que ambas situaciones reflejan el mismo riesgo: la dependencia excesiva de la IA puede debilitar habilidades fundamentales, tanto en estudiantes como en profesionales. Un desarrollador que ya no lee un stack trace y un estudiante que ya no consulta fuentes tienen mucho en común: ambos dejan de ejercitar el pensamiento crítico.

There's a harsh reality facing development teams in 2024: according to recent studies, 90% of all IT projects are delivered late due to manual testing. Yet despite this staggering statistic, the majority of businesses still do little to no functional test automation. This creates what we might call the "testing paradox"—teams know manual testing is slowing them down, but they continue to rely on it anyway. Meanwhile, the costs are mounting in ways that extend far beyond delayed deliveries. 48% of respondents in the latest State of Quality Report identified lack of time as the top challenge in achieving software quality goals. But here's what's really happening behind those numbers: The average development team wastes 14 to 16 hours every week wrangling internal tools, setting up environmen…  ( 8 min )

When building interactive web applications, managing event listeners efficiently is crucial. Adding event listeners to every element individually can hurt performance—especially if the DOM has hundreds or thousands of elements. That’s where Event Delegation in JavaScript comes to the rescue. In this blog, we’ll cover: 🔎 What is Event Delegation in JavaScript? Event Delegation is a JavaScript technique that leverages event bubbling to handle events more efficiently. Instead of attaching event listeners to multiple child elements, you attach a single event listener to a parent element. The parent listens for events bubbling up from its children and handles them appropriately. ⚡ How Event Delegation Works Event Bubbling – When an event occurs (like click), it bubbles up from the target eleme…  ( 7 min )

.NET 9 has been out for almost a year now, but most developers are still using it like .NET 8. The real gains aren't in the headline features.

Multi-string search becomes efficient. Async coordination gets simpler. Testing private members becomes fast. Collection lookups get faster. Memory management becomes smarter. Most teams ship .NET 9 apps that perform like .NET 6 because they stick to old patterns. The developers using these features are already building faster systems while others struggle with familiar bottlenecks. I've been running .NET 9 in production for months now, and honestly, I can't go back. When I see 20-30% faster response times and better memory usage, sticking with older versions feels like driving with the parking brake on. The performance gains aren't just nice to have anymore, they're real money left on the table."  ( 6 min )

Learning SQL Data Types & Operators Today marks Day 17 of my Data Analytics learning journey, and I explored one of the most important topics in SQL – Data Types and Operators. These are the foundation for writing queries correctly and performing meaningful operations on data. To practice, I also created a Hospital database using different data types and applied SQL operators to perform calculations and comparisons. In SQL, every column in a table must have a data type. Data types tell the database what kind of values can be stored in a column (numbers, text, dates, etc.). Here are the main categories of SQL data types: Numeric Data Types INT → Whole numbers (e.g., 10, -5, 1000) DECIMAL(p,s) → Fixed precision decimal values (e.g., 123.45) FLOAT / REAL → Approximate decimal values (e.g.…  ( 7 min )

Cross-Site Request Forgery (CSRF, pronounced "sea-surf") is a sneaky and dangerous web vulnerability. Classified as CWE-352 by MITRE, it allows attackers to trick authenticated users into unknowingly submitting malicious requests to a web application. Imagine being logged into your bank account and clicking a seemingly harmless link that secretly instructs your browser to transfer funds to an attacker – that's CSRF in action. Why CSRF is Dangerous (CWE-352): Exploits Trust: The target site trusts the user's browser because it sends valid session cookies automatically with every request. User Unawareness: The victim executes the malicious action entirely unknowingly, often with a single click. Impact: Can lead to account takeover (changing email/password), unauthorized fund transfers,…  ( 7 min )

Introduction As software projects grow, so do their repositories. Large binary files, extensive histories, and sprawling codebases can turn simple Git operations into time-consuming ordeals. Cloning a repository shouldn't feel like downloading the entire internet, and checking out a branch shouldn't require a coffee break. Git Large File Storage (LFS) and sparse-checkout are two powerful features designed to solve these exact problems. Git LFS efficiently manages large binary files by storing them outside your repository, while sparse-checkout allows you to work with only the parts of a repository you need. Together, they transform unwieldy repositories into manageable, efficient development environments. This guide will show you how to implement both solutions, optimize your workflow fo…  ( 13 min )

Official announcement: Pricing plans are live Who’s affected by the new pricing plan Requires Kiro v0.2.13 or higher. Check from the profile menu in the top-right corner of the editor.

If you’re curious about how AI systems like Claude or ChatGPT connect to external tools and data sources—and why MCP matters—this blog is for you. We’ll break it down in simple terms. MCP stands for Model Context Protocol. It’s an open-source standard released by Anthropic in November 2024. Think of MCP like a USB-C port for AI. Just as USB-C lets you connect different devices to your computer with the same cable, MCP lets AI systems connect with different tools, databases, or apps through one common protocol. No more custom connectors: Previously, developers had to build a separate integration for every AI-tool pair. MCP eliminates that need by providing a standard interface. Avoids “MxN problem”: With many AI models (M) and many tools (N), the combinations grow exponentially. MCP stream…  ( 7 min )

Vibe coding has quickly shifted from an insider buzzword to a mainstream method shaping how software gets built. At its core, this practice lets programmers and analysts describe what they want in plain language, then rely on powerful AI to do the heavy lifting—turning ideas into working code in a fraction of the usual time. The appeal is simple: speed, creativity, and a lower barrier to entry for those who aren’t expert coders. This trend isn’t just about making coding easier. It’s about changing the coder’s role from line-by-line writer to idea architect and quality czar. AI now shoulders much of the grunt work, freeing professionals to focus on high-level structure, design, and ensuring quality. Businesses like startups and enterprise teams embrace vibe coding for fast prototyping and c…  ( 15 min )

Is your Java app struggling? Are users complaining about slow responses or frozen screens? You might be facing a silent killer hiding in plain sight: a common thread pool mistake. We've all been there. You've built a fantastic Java application, it's robust, it's feature-rich, but then you launch it, and… it's sluggish. It chokes under pressure. The server looks fine, memory isn't maxed out, but the performance just isn't there. What if I told you the culprit often isn't your brilliant algorithms or fancy new libraries, but something as fundamental as how your application handles concurrent tasks? Specifically, how you set up your thread pools. Think of a thread pool like a team of workers ready to tackle tasks. Instead of hiring a new worker (creating a new thread) for every single job tha…  ( 9 min )

Call of Duty: Black Ops 7 is reportedly landing on November 14th this year, hitting virtually every major platform—from PS4 and Xbox One to the latest consoles—though Switch 2 owners might have to wait a bit longer. Thanks to Microsoft’s pact with Nintendo, a Switch port seems inevitable, it’s just a matter of timing. In other gaming news, long-time Solid Snake voice actor David Hayter finally played Metal Gear Solid 5: The Phantom Pain—a game he missed out on back in 2015 when Keifer Sutherland took over—and he thinks it’s “amazing.” Plus, a quick look at how all your Borderlands 4 Vault Hunters can team up to take down the next big boss.

The latest “Designing Amon” video pulls back the curtain on how the Borderlands 4 team built their biggest Vault Hunter yet—from concept sketches and performance capture to final in-game model. Plus, mark your calendars: Borderlands 4 drops on PS5, Xbox Series X|S and PC on September 12, 2025, and on Nintendo Switch 2 on October 3, 2025. Amon’s origin? He grew up worshipping Vault monsters—until one turned on his cult and he was the only survivor. Now he’s a monster-slaying warrior-poet: tough as nails but always ready with a war story or sage advice for his fellow Vault Hunters. Watch on YouTube  ( 5 min )

Imagine the last time you used an app or visited a website—maybe you ordered food online, scrolled through social media, or checked your bank account balance. Have you ever wondered how that software was built? The challenge? For beginners, the sheer number of options can feel like an endless maze. I recently came across this brilliant mind map (below) that cuts through the noise and makes web development simple. It clearly breaks the field into two main pillars—Front End and Back End—and organizes the key languages, frameworks, and tools you’ll encounter. If you’ve been unsure where to start, this visual guide—paired with step-by-step resources from roadmap.sh—can be the map that leads you from zero to confident web developer.

Introduction There is a proverb: “After victory, tighten your helmet strap.” When people get an early sense that something is working, they tend to want to push forward. But that very feeling of momentum can distort judgment and become the trigger for overlooking the next pitfall. The sense of “it’s going well” is an important signal that can indicate success, yet at the same time it can become a trap. When something seems to be going well, the brain shortcuts to “this approach is correct” (overconfidence bias) and selectively filters for information that fits its expectations (confirmation bias). As a result, people skip re-examining assumptions and fail to recheck risks, scaling up based on a skewed view—small oversights can cascade into catastrophic defeat. In Japan’s Sengoku period,…  ( 7 min )

The Grand Illusion of "Future-Proof" Code Ah, the siren song of scalability. It whispers sweet nothings into our ears: "Build it right the first time," "You’ll thank yourself later," "What if you get 10 million users tomorrow?" And before you know it, you’ve spent three months architecting a dazzling microservices masterpiece, only to realize your "scalable" app has exactly one user: you, refreshing the page in incognito mode. This was me. I was that developer. Convinced that my side project needed a Kubernetes cluster, a distributed notification system, and a payment service that could handle Stripe-level traffic, despite the fact that my MVP was still just a glorified to-do list.

Quality issues rarely start with a major failure. It’s usually a series of small events—a test that fails, a late shipment due to a recheck, or a batch flagged for retesting. On their own, these seem minor. But over time, they cost time, money, and customer trust. This post shows how to use the data you already collect in Business Central to uncover patterns, take action, and improve quality using tools like Excel and Power BI. Business Central can collect a lot of test-related data—from pass/fail grades and timestamps to supplier info and field values. But most teams review one record at a time or pull reports without clear trends. As a result, it’s hard to answer questions like: Why does a specific test fail repeatedly? Is one supplier more prone to quality issues? Do quality failures …  ( 6 min )

Large Language Models are powerful, but they're also resource-intensive. Every query, no matter how simple, consumes expensive computational cycles. I realized a huge chunk of my server costs was from the LLM repeatedly answering "hello," "thanks," and "ok." These queries are a waste. They don't teach the model anything new. They don't require complex reasoning. They are pure resource drain. My first thought was to filter them out on the client-side. But that creates a manual chore—I'd have to constantly update the list of simple phrases. That approach doesn't scale. So, I flipped the problem on its head. What if the LLM could solve this problem itself? The core idea is this: I created a system where the LLM itself decides which queries are too simple for its attention and teaches a client…  ( 6 min )

Securing Your Code Like You Secure a Storefront: Lessons from Iron Bollards You ever walk past a row of iron bollards and think, “Huh… these things are just standing there, but they’re actually protecting everything behind them”? I had that moment last week while grabbing coffee downtown. And oddly enough, it got me thinking about code security. A few years ago, I pushed a “quick fix” into production without testing it thoroughly. Yeah, I know—rookie move. It worked fine for a couple of hours… until it didn’t. That’s when I realized the value of strong, visible defenses. In real life, you might have iron bollards installations Chicago to keep reckless cars from smashing into a storefront. In code, those defenses are your validation layers, access controls, and security reviews. Bollards …  ( 6 min )

Understanding YAML's Critical Role in DevOps Automation and Infrastructure as Code In the ever-evolving landscape of DevOps, one technology has become the universal language for configuration management, automation, and infrastructure as code: YAML (YAML Ain't Markup Language). From Kubernetes manifests to GitHub Actions workflows, from Ansible playbooks to Docker Compose files, YAML has emerged as the de facto standard for defining infrastructure, configurations, and automation pipelines. This article explores why YAML has become indispensable in modern DevOps practices and how it's shaping the way we build, deploy, and manage applications in the cloud-native era. YAML is a human-readable data serialization format designed to be simple and expressive. Unlike JSON or XML, YAML emphasizes r…  ( 10 min )

Security has become a buzzword; every company wants to claim its product or service is secure. But is it? Before we start discussing the different security principles, it is vital to know the adversary against whom we are protecting our assets. Are you trying to stop a toddler from accessing your laptop? Or are you trying to protect a laptop that contains technical designs worth millions of dollars? Using the exact protection mechanisms against toddlers and industrial espionage actors would be ludicrous. Consequently, knowing our adversary is a must so we can learn about their attacks and start implementing appropriate security controls. Before we can describe something as secure, we need to consider better what makes up security. When you want to judge the security of a system, you need t…  ( 14 min )

If an attacker successfully bypasses a firewall via a legitimate-looking connection and then performs any malicious activities inside the network, there should be something to detect it timely. For this purpose, we have a security solution inside the network. This solution is known as an Intrusion Detection System (IDS). Think of an example of a building’s security. A firewall acts as the gatekeeper, checking the people coming in and going out. There is always a chance that some bad actor will successfully sneak inside and start performing malicious activities. He was missed at the gate, but what if we catch him even after he gets in? This can be done by the surveillance cameras present throughout the building. The IDS plays the role of surveillance cameras. It sits in a corner, monitors t…  ( 11 min )

Software supply chains have become a focal point for attackers, as modern applications rely heavily on third-party and open-source dependencies.

I’ve been using AI daily for creative and strategic work for years. But after a recent update changed the behavior of my primary assistant — despite the same prompts — I realized something: personal nuance doesn’t survive at scale. Large AI systems must follow global rules, minimize risk, and standardize outputs. That’s fair. But it also means they can’t preserve the subtle, evolving rhythm of a one-on-one collaboration. So I’m stepping back. I’m not launching a product. This week, I began Week 1 of building Kai Lite — the mobile layer of a three-part architecture I’ve been planning.

What is system design? System design is the process of defining the elements of a system, as well as their interactions and relationships, in order to satisfy a set of specified requirements. It involves taking a problem statement, breaking it down into smaller components and designing each component to work together effectively to achieve the overall goal of the system. What does this mean? System design is that planning stage in software engineering where you design the flow, patterns, architecture of how the system you're trying to build becomes functional and efficient, taking better steps to build a better system. So you're asked to build an authentication system and yeah, you probably already know how to build one but those that actually satisfy the requirement of the project? This is the very big question to ask as a software engineer designing a system. It starts from as little as the language, framework to use. This is a very important question and I'll be going through a few steps as to how you can approach it and build a better system Understand the problem: Identify the scope of the system: Create a high-level design: Continuously monitor and improve the system: continuously. This is just an introduction to my series on system design. I will be dropping some system design concepts in the next one.  ( 6 min )

Image formats like PNG and JPG are classified as raster formats. These formats are made of a matrix of pixels. The problem with these images is that they don't upscale well — in other words, if you make the image larger, its definition will decrease. An SVG is a different kind of image. It is a Scalable Vector Graphic (SVG) and it uses equations to plot the image. In that way, the definition of the image won't change when we change its scale. We can use SVG images in HTML with the tag . Example: <path d="M35 65 Q50 80 65 65" s…  ( 6 min )

Exceptions in Java are represented through a structured class hierarchy, rooted in the Throwable class. This hierarchy helps developers categorize and handle different error conditions efficiently, whether they are recoverable or not. At the top of the Exception Hierarchy is the Throwable class. It has two direct subclasses: Error: Represents serious problems that applications should not try to catch. Exception: Indicates conditions that a program might want to catch. Throwable ├── Error └── Exception "To handle exceptions effectively, you must first understand where they come from." The Error class and its subclasses represent critical conditions, such as OutOfMemoryErr…  ( 6 min )

Author: Charith Amarasinghe Since the beginning, Railway’s compute has been built on top of Google Cloud Platform. The platform supported Railway's initial journey, but it has caused a multitude of problems that have posed an existential risk to our business. More importantly, building on a hyperscaler prevents us from delivering the best possible platform to our customers. It directly affected the pricing we could offer (egress fees anyone?), limited the level of service we could deliver, and introduced engineering constraints that restricted the features we could build. And not only is it rare that we understand why things break upstream, but also despite multi-million dollar annual spend, we get about as much support from them as you would spending $100.

API documentation is broken. You've likely seen it: endpoints that don't exist anymore, missing response codes, or a lingering "TODO" in a YAML spec. And that's assuming there's a spec at all. The core issue? Most developers don't enjoy maintaining documentation. Manually editing OpenAPI specs or annotating endpoints with docstrings is tedious, repetitive, and error-prone. Modern tools try to ease this pain, but each comes with its own trade-offs. Tools like Postman allow you to build collections and export them as OpenAPI specs. This is certainly better than hand-writing YAML, but it's still manual work. You need to remember to update your collections every time you change an endpoint, add parameters, or modify response structures.

Today, my trainer, Muthu Sir, organized a hackathon-like event, and it was an amazing learning experience for me. During the session, I learned how to create a CSV file using Java. I practiced writing structured data into the file, like IDs, names, ages, and departments, which was really interesting. After that, I learned how to read and write CSV files in Java. Using BufferedReader, I could read each line, split the values, and even skip the header or empty lines. It gave me a clear understanding of how data can be handled programmatically. The most challenging part for me was Java Database Connectivity (JDBC). I initially faced several difficulties while trying to store CSV data into a PostgreSQL database. I struggled with connecting to the database, writing proper SQL queries, and handling errors like duplicate primary keys. With step-by-step guidance from ChatGPT, I finally fixed all the errors. I learned to use batch inserts for efficiency, and ON CONFLICT statements in PostgreSQL to handle duplicates. Now, my Java program can read CSV data, print it in a table format, and insert it safely into the database. Overall, this hackathon helped me practically apply Java skills, understand file handling, and learn how to integrate Java with databases. It was a proud moment when I successfully completed the task, and I feel more confident about working with Java and JDBC in real-world scenarios.  ( 6 min )

Recently, I found myself reflecting on this paradox after watching Celeste Headlee's brilliant TED Talk on better conversations than the why Tech leader like Elon Musk or Steve Jobs style. Headlee argues that we've lost the ability to talk to each other. We text instead of talk. We prepare rebuttals instead of listening. We multitask instead of focusing.

Securing SSH access is a top priority for any Linux server, and relying on passwords alone is no longer sufficient against modern attacks like credential stuffing and brute force attempts. Adding multi‑factor authentication (MFA) to SSH hardens access by requiring something known (key or password) plus something possessed (a one‑time code or hardware key). Why MFA for SSH is Needed? Reduces risk from password reuse and brute‑force attacks by requiring a second factor even if a credential is compromised. Integrates cleanly with existing SSH setups using PAM without replacing SSH keys or existing workflows. Ubuntu includes enhanced support for FIDO/U2F, enabling hardware‑backed second factors for stronger, phishing‑resistant authentication Prerequisites: Ubuntu 20.04 server with SSH access …  ( 6 min )

Start-here.page=About.post 📅 Date: 2025-08-14 🔧 Tools: USB with Debian 13 How It Started It all started when I realized that my system, even after removing the GUI, was still heavy. It was a great experience troubleshooting the issues that came after deleting the GUI along with a bunch of variables and caches. I used sudo apt --purge and ended up losing SSH, drivers, and a bunch of other things. I managed to fix most of them, but the system was already a mess. So today, I rebooted and installed a fresh Debian 13 (light) on my server. The Problem Removed almost all network components. Deleted drivers, especially ath10k_pci (internet-related). Made a big mess in the file system. Had trouble with a 5G Wifi connection — Debian 12 wouldn’t let me use my 5Gb internet because it wasn’t friendly with my drivers. The Fix Most file system issues were solved after spending a lot of time cleaning things up. I created one main directory for everything and built a tree with manuals and notes inside it. The network was trickier — I had to use a USB stick, find the right driver manually, download it, and then set up wpa_supplicant & wpa_passphrase to create the first connection. After that, I installed Network Manager. The 5G issue wasn’t completely solved. I replaced my firmware with a newer one, which gave me a 5G connection, but the speed was only 15 Mb/s. In the end, I decided to completely erase the system. First, I created a tar -czf backup of the main directory and saved it to an external drive. Then I installed Debian 13 — now I’m building my environment from scratch, starting with a clean 1.4 GB base. What I Learned How to set up a network connection from scratch. How to organize space better. How to create a personalized environment. How to use usermod to rename the server (did it twice). Gained a deeper understanding of my system.  ( 6 min )

Choosing the right module system in Node.js can make or break your development experience. Understanding the difference between CommonJS (CJS) and ES6 Modules (MJS) is crucial for modern JavaScript backend development. CommonJS is Node.js's original module system, introduced when the platform launched in 2009. Think of CJS like checking out a book from a traditional library – you use require() to "borrow" functionality from other files, and module.exports to "lend out" your code to others. CJS uses synchronous loading, meaning modules are loaded and executed immediately when required. This approach works perfe…  ( 7 min )

Enterprise AI often hits a wall. Pilots perform well and dashboards look great, but when it’s time to scale across functions, the system starts to fall apart.

They unfold across systems, where inputs interact, feedback loops form, and new conditions constantly reshape the landscape. The Problem Isn’t the Output, It’s the Structure.

Introduction Sensitive data leaks are one of the most common — and most preventable — security incidents in software development. From database passwords showing up in logs to API keys being printed in debug output, even experienced developers have made this mistake. That’s why I built PyShield-Secure, a Python library that makes it almost impossible to expose sensitive variables by accident. Whether you’re building a web app, CLI tool, or microservice, PyShield-Secure helps you keep your secrets… secret. The Problem In plain Python, sensitive variables can easily: Appear in print() statements Show up in debug logs Be left in memory long after use Be accessed without control in multi-threaded environments How PyShield-Secure Solves It ✅ Smart Masking – Sensitive values are replaced with ***** when printed or logged. Real-World Use Cases Hiding database credentials in production logs Securing API tokens in cloud environments Preventing accidental leaks in debugging sessions Auditing access to sensitive values in high-security projects Why Developers Love It Unlike storing secrets in environment variables only, PyShield-Secure actively protects them in memory. Even if you accidentally print the variable, the actual value stays hidden. Get Started Now Protect your Python projects with one command: pip install pyshield-secure 📦 PyPI: https://pypi.org/project/pyshield-secure/  ( 6 min )

I often encounter programming terms and lingo that goes way over my head when I'm browsing software engineering content on the internet. I wish that I could say that I drop everything and search these terms as soon as I see them, but this is rarely the case. But, this article is about a time that I took my medicine and not only looked up something I didn't understand, but implemented it into my daily workflow. The term? —dotfiles Maybe you're more hip than I was, but if you're not, let me fill you in. Dotfile is technical shorthand for a hidden file on your system that provides configuration settings to your operating system, shell, or applications. Most systems' preferred method of hiding files s to add a . at the beginning of the file—hence, dotfile. Many developers choose to alter the…  ( 11 min )

tl;dr: founding full stack engineer (leaning front-end), 150k-220k + 0.5-1.5% equity, SF🌞 As we all know, the best arguments come to mind after the conversation, when you’re stuck in a traffic jam or standing in the shower — and that’s where they die, too. But this is humans. Leaping AI’s voice agents remember all of their shower thoughts and improve after each interaction 🛁 It’s a YC startup that is top-1% on revenue in their batch, having doubled it over the 10 weeks at the accelerator. They have raised $4.8M: among the investors is Paul Graham, who only invests in 3-4 startups a year. Even though the agents are self-improving, right now they need a little help from a Founding Full Stack Engineer that’s focused on frontend: ⏹️ TypeScript + Next.js, or experience with a similar stack; The last part is crucial: you don’t need to be told what to do, you have ideas and get them shipped, you’re opinionated and know how to communicate well — and, most importantly, you love all of this 💓 You’ll be joining a super-early stage project, with a million interesting tasks, a chance to build the engineering culture from ground up, and full ownership of features — from a client's idea all the way to production deployment. And equity, of course! 😇 The pay is $150k-220k + 0.5-1.5% equity. The office is in San Francisco, but you can start remotely and relocate later via O1. If you're already in SF, that's perfect!

The Problem That Started Everything 🤔 Last week, I watched a real estate agent friend spend 30 minutes copying WhatsApp messages into a spreadsheet. Minutes. Of. Copy. Paste. That's when it hit me - thousands of businesses waste hours daily extracting lead information from WhatsApp conversations. I built a simple REST API that converts this: sarah@techcorp.com Into this: json { "name": "Sarah", "company": "TechCorp", "email": "sarah@techcorp.com", "phone": "555-0123", "requirement": "office space downtown", "budget": 5000 }  ( 5 min )

If raw execution speed was the only metric that mattered, Python wouldn’t stand a chance against compiled languages like C, Clang, or Rust. Benchmarks don’t lie: a billion nested loop iterations might take 0.50 seconds in C or Rust, while Python—interpreted, dynamically typed, memory-managed—might stretch that into many, many more. And yet, Python continues to dominate in data science, machine learning, backend development, automation, and beyond. So why does a “slow” language keep winning hearts (and GitHub stars) year after year? Performance is not only measured in CPU cycles—it’s also measured in time-to-solution. Your code could execute in 0.5 seconds, but if it takes you three days to write and debug, you might lose more productivity than you gain from runtime speed. Python’s design c…  ( 6 min )

If you’ve ever led a development team, you know leadership in tech isn’t just about shipping features—it’s about building the right environment for those features to get built well. Pull requests, stand-ups, sprint planning—they all matter. But beneath the tooling and processes, there’s a deeper layer: trust, alignment, and continuous improvement. And these are the areas where even the most technically skilled leaders can struggle. The Developer Leadership Dilemma Tech leaders often rise through the ranks because they’re great engineers, not because they’ve been formally trained to lead people. The shift from “I write code” to “I enable others to write better code” can feel like an entirely new career.

We’re big fans of the Awesome AI tools list and we all use it to discover new AI tools over at Portia AI. My latest and favourite find is Merlin: A Chrome extension that allows me to ask “how to” questions on any app rather than flipping over to ChatGPT or Claude to ask. Here are five tools we use a lot and wish were on the Awesome AI Tools list: Textual – We love spicing up our terminal interface for using the Portia SDK and even non-technical customers love it when I run demos from the terminal now. We all have our favourite terminal flavour of it – I made mine with Atari retro vibes 🕹️holler if you’re using Portia and want the code for it! Mistral OCR – We think it’s the best balance of cost, speed and performance for OCR on the market right now. We also admittedly have soft spot for our neighbours across the English Channel over in La France 🥐. Visily – Figma for non-designers, it’s my go-to when brainstorming early UX mocks with front-end engineers and UX designers. I especially love the ability to turn any screenshot into a wireframe because I can bring inspirations to life with some tweaks super quickly. Podcastfy – I can’t say for sure why they skipped the “i” in their name but we love that they are an open source and equally powerful alternative to NotebookLM. One of our engineers built a bite-sized AI news podcast that I listen to during my commute daily. You can recreate it here using Portia SDK or get the daily podcast on our Discord server’s #ai-news channel. OpenRouter - We love OpenRouter because it allows you to easily try out new models and load balance between models. We actually got an open source contribution for this one recently, so we should be supporting it ❤️  ( 6 min )

Hi everyone! I’m a young builder from Sri Lanka working on something pretty unique: an AI-powered speedcubing timing app that also generates cubing lessons based on your solves. I’ve built the whole thing solo using AI tools—without knowing how to code. It’s mostly working, but now I’m stuck. Bugs keep popping up, and AI can’t fix them reliably anymore. Every fix leads to new errors, and I’ve hit the limit of what I can do alone. I’m not looking for a full team—just one person who knows front-end dev (JavaScript, HTML, maybe a bit of API handling) and can help me debug and refine the site. If you love cubing, coding, or just want to help a passionate young builder finish something cool, I’d be super grateful.

Why I Built This (The Honest Version) I wasn't trying to solve some massive problem or disrupt an industry. I just thought SVG animations were underutilized on the web, and the barrier to creating them was unnecessarily high. The Stack Core Architecture Text input → LLM processing → SVG output Community library for sharing animations Copy-paste workflow (no downloads, no accounts required for basic use) The interesting challenge was prompt engineering for consistent SVG output. LLMs are great at code generation but terrible at maintaining consistent animation timing and valid XML structure. Real Numbers from Google Analytics Real Numbers from Admin panel of SVGenius Free-First Strategy No paywall on core functionality. Community Library Users publishing their animations created a flywheel effect. More content → better SEO → more users → more content. Copy-Paste UX No forced downloads or complex export flows. Generate → copy → paste. Developers appreciate efficiency. Underestimated Prompt Engineering Complexity Getting consistent SVG output from LLMs is harder than expected. Spent weeks fine-tuning prompts for edge cases. SEO Was an Afterthought Should have optimized for search from day one. Adding proper meta tags, sitemap, and structured data later was more work. Analytics Setup Took 2 weeks to properly implement tracking. Lost valuable early user behavior data. Community Features Users wanted search, filtering, and categories in the library much earlier than I provided them. Performance Matters AI Consistency is Hard Community > Features Note: I'm sharing real numbers This isn't about replacing GIFs (though you could). It's about having another tool in the performance toolkit: Scalable: Perfect on any screen density Lightweight: Usually under 1KB Accessible: Work with screen readers Customizable: Change colors/timing with CSS SEO-friendly: Searchable content Try It Out svgenius.design The tool is free, takes 30 seconds to try, and might solve a problem you didn't know you had.  ( 6 min )

Baby steps but We'll get there I recently built a Boston House Price Prediction app using Linear Regression, Streamlit, and Render. It was a great learning experience, and I’m happy with how it turned out. I started by exploring the Boston Housing dataset, cleaning it up, and normalizing the features with StandardScaler. After splitting the data into training and test sets, I trained a Linear Regression model using scikit-learn and evaluated its performance with metrics like R² score. Once the model was ready, I saved it along with the scaler using joblib. For the frontend, I used Streamlit to create a simple, interactive interface where users can adjust input values—like crime rate, number of rooms, and accessibility—and see the predicted price update instantly. Instead of using Streamlit’s default sharing, I deployed the app on Render for more flexibility. I set up the project with all the necessary files—app.py, model.pkl, requirements.txt, and a render.yaml config—and connected it to GitHub for seamless deployment. This project helped me bridge the gap between machine learning theory and real-world application. If you're interested in the code or deployment process, I’d be happy to share more details! use the link below to view the live project https://boston-house-price-prediction-2csd.onrender.com/ live model MachineLearning #DataScience #Python #LinearRegression #Streamlit #Render  ( 5 min )

Sometimes, as developers, we need to share query results with teammates maybe to explain a bug, show app behavior, or provide visibility into some data. Often, this means copying directly from the terminal. Pasting raw SQL output into a text editor or a spreadsheet usually ends in a chaos 😫😤😞. Everything dumped into a single cell, broken formatting, unreadable messes 🥴. And yet, putting this data into Google Sheets is super helpful: it’s clear, searchable, and collaborative. But exporting to CSV just for that? Too much friction. Here’s a dead-simple way to copy query results from psql and paste them cleanly into Google Sheets—no CSVs, no cleanup, no formatting pain. psql: psql -U your_user -d your_database \x off \pset format unaligned \pset fieldsep '\t' SELECT id, name, email FROM users LIMIT 10; 😲 Each column goes perfectly into its own cell row drops nicely into a separate row No CSV.

SASE blends networking and security in one platform. Think SD-WAN for smart routing paired with cloud security controls like Secure Web Gateway, CASB, ZTNA, and Firewall as a Service. Policies follow users and devices wherever they connect, and global points of presence keep performance consistent. SSE focuses only on security services. It delivers SWG, CASB, and ZTNA from the cloud without touching your existing transport. If your SD-WAN and routing are already in place, SSE layers modern protection on top, giving you faster time to value. Zero Trust underpins both models.

The Case for AI Provenance: Why We Need to Trust the Source AI can now create blog posts, images, code, and even research papers in seconds. That’s exciting — but it’s also dangerous. If you’ve ever asked yourself, “Can I trust this?” when reading AI-generated content, you’ve stumbled into the problem of AI provenance. In simple terms, provenance is the origin story of a piece of content — where it came from, how it was made, and how it’s been changed along the way. For AI, that means tracking: Metadata — model name, version, generation date, prompt Audit trails — every transformation applied to the content Source attribution — the original datasets, documents, or media used Think of it as a “nutrition label” for AI output. Fake news and deepfakes spread fast. Provenance allows platforms…  ( 6 min )

We as angular developers have long relied on RxJS BehaviorSubject for managing reactive state. But with the introduction of Signals in Angular 16+, there's now a simpler, built-in alternative. So, should you replace your BehaviorSubjects? Let's break it down. BehaviorSubject (RxJS): Emits the latest value to subscribers, supports streams & reactive programming, widely used before Angular Signals. Angular Signals: A new reactivity model introduced in Angular 16+, allows fine-grained reactive updates without RxJS complexity. // BehaviorSubject Example import { BehaviorSubject } from 'rxjs'; const count$ = new BehaviorSubject(0); count$.subscribe(value => console.log(value)); // 0 count$.next(count$.value + 1); // emits 1 // Signal Example import { signal } from '@angular/core'; const count = signal(0); console.log(count()); // 0 count.set(count() + 1); // 1 Use Signals if: You want simpler, built-in state management. You don't need complex async operators. You want automatic fine-grained change detection. Use BehaviorSubject if: You already have heavy RxJS usage. You need operators like map, filter, debounceTime. You're integrating with streams, websockets, or external APIs. Signals can be faster for component-level state because they avoid unnecessary change detection. BehaviorSubject is still better for large async workflows or event streams. If you're starting fresh → prefer Signals for simplicity. If you have an existing RxJS-heavy app → stick with BehaviorSubject until you can gradually refactor. 💡 Verdict: Signals are the future for local Angular state, but RxJS (and BehaviorSubject) isn't going anywhere for complex reactive pipelines.

Let's delve into the world of monitoring and discover how it intertwines with the core principles of DevOps. Monitoring in DevOps is not just about tracking metrics; it's about gaining insights into the system's behavior, identifying anomalies, and proactively addressing issues before they escalate. By continuously monitoring key performance indicators (KPIs) such as response times, error rates, and resource utilization, teams can maintain a robust and resilient infrastructure. While monitoring focuses on collecting data, observability takes it a step further by emphasizing the ability to understand and debug complex systems. With observability, teams can trac…  ( 6 min )

Imagine you’ve just finished designing a new PCB for a wearable device, and you can’t wait to see it in action. But what if that board overheats or shuts down randomly? Frustrating, right? An ICT test examines a fully assembled PCB all at once, instead of checking each component one by one. Think of it as a comprehensive “health check” for your board: Component Accuracy Verifies resistors, capacitors, diodes, chips, and connectors are the correct types and values. Electrical Performance Confirms voltage and current pathways behave exactly as designed.

AI is evolving fast, and this evolution is fundamentally changing what businesses expect from their technology. Organizations are no longer satisfied with tools that simply follow orders. They now demand systems that can think ahead, adapt in real-time, and deliver results without constant human input. This is where agentic workflows come in. They help us build AI systems that can perform more tasks independently, making decisions and utilizing tools to achieve goals without constant human intervention. In this blog, we'll explore what agentic workflows are, how they differ from AI workflows, common design patterns, and their benefits and challenges. If you're looking to build smarter AI systems, agentic workflows offer a strong advantage. Agentic workflow is a system where AI agents can m…  ( 13 min )

The clothes you wear to a country concert can make or break your night. The music scene in Wilmington has everything from honky-tonk music that makes you want to stomp your boots to modern country pop. Your clothes should fit the mood and keep you comfortable. First, Get to Know Your Venue You need to look different in different places. Amphitheaters outside get hot and dusty. Indoor places stay cooler, but they are crowded.

Problem You can see "data scanned" metrics for queries in the Redshift console, but you need to access these numbers programmatically from Lambda functions, ETL jobs, or CI/CD pipelines that use the Redshift Data API. Without programmatic access to scan metrics, you can't implement cost monitoring, fail-fast logic, or automated performance telemetry. This isn't about querying historical performance data or setting up dashboards — it's about getting the exact "total data scanned" number for any specific query executed via the Data API. The challenge is mapping Data API statement IDs to Redshift's internal query system and extracting scan metrics programmatically. Programmatic access to scan metrics enables critical operational capabilities like automated cost controls that fail jobs excee…  ( 8 min )

This is part 3 in the SBOM series of blog posts As there was no support yet in Raku for any of the SBOM standards, it was a question for which standard I should be developing: SPDX 3.0.1 or CycloneDX 1.6. For better or worse, I selected CycloneDX because it was recommended (thanks Salve!) and because it had better readable / browsable specification. Because implementation of this would require a lot of reading and browsing! So by the end of June I started working on this, and the first version of the SBOM::CycloneDX was uploaded on July 7th. With the release 0.0.15 uploaded just the other day. It turned out to be one of the largest single distributions I ever worked on: 125 classes (spread out over 51 files), 51 enums and 25 subsets, created by 5000+ lines of code and inline documentati…  ( 8 min )

If you've ever struggled to move files between your Android device and PC without cables, this guide will change the game. Using Termux, you can create a simple, secure, and wireless way to sync files. Whether it’s documents, images, or backups, this setup ensures you never have to plug in a USB cable again. Most people still transfer files using USB cables or cloud services. While cloud services are convenient, they often come with storage limits and privacy concerns. Syncing via Termux keeps your files local, private, and completely under your control. Plus, this method works even if you have limited internet access, unlike cloud-based solutions. If you want to strengthen your security further while syncing, consider reading my guide on Surfshark VPN and best VPNs for Termux to ensure yo…  ( 7 min )

In today’s fast-paced digital landscape, businesses are increasingly adopting APIs for Translation to bridge language gaps and serve a global audience. These APIs allow developers to embed translation capabilities directly into applications, websites, and platforms—enabling instant multilingual support without manual intervention. But before you integrate one into your workflow, it’s important to understand what these APIs can (and can’t) do, and how to choose the right API for your needs. At their core, APIs for translation are sets of endpoints that enable developers to send text, documents, or speech for automated translation between languages. Instead of relying on standalone tools where someone pastes text into a box, these APIs process translations seamlessly in the background—wit…  ( 8 min )

We’ve all seen it. A single API endpoint makes three, four, sometimes ten separate queries to load one page. The developer is “being clever” by running them in parallel with Task.WhenAll or async calls. From the client’s perspective, it feels faster. Quick Note: What is Dapper? Dapper is a micro-ORM (Object Relational Mapper) for .NET, created by the Stack Overflow team. Fast — performance close to raw ADO.NET Lightweight — no complex change tracking, minimal overhead Simple — you write your own SQL and map directly to C# objects Why use Dapper here? Full control over the SQL being sent Supports QueryMultiple, which lets you fetch multiple result sets in one roundtrip Perfect for performance-sensitive, read-heavy workloads The Scenario You want to display: Order header Order items Shipping…  ( 8 min )

Let’s be honest. There’s a fear hanging in the air — not just in the game dev community, but everywhere. A thick, almost tangible fear, the kind you feel you could spread on bread instead of butter. It seeps through every other thread on X (formerly Twitter), in hushed Discord debates, and in the headlines of the less-than-brilliant press. And this fear has a name — Artificial Intelligence. And you know what? Talking about it feels absurd to me. Not because I don’t see the problem, but because we’re discussing the wrong thing entirely. There’s nothing inherently wrong with AI — just as there’s nothing wrong with a hammer, electricity, or code itself. The problem is not in the tool. The problem is in the hand that’s afraid to pick it up, and in the eyes that are afraid to see what the tool …  ( 14 min )

Below is a compact, field-tested roadmap for building a multitasking scheduler on a microcontroller—starting simple (cooperative) and moving to a true preemptive scheduler (Cortex-M example).

Storing customer information is a fundamental part of running a business. For companies like fintechs, this goes beyond just names and emails. They often need to store user profiles, authentication details, bank account information, transaction records, API logs, and more. But figuring out the best way to store all this data isn't always simple. There are industry standards and regulations that must be followed to ensure the business operates safely and remains compliant. Fintechs also generate a massive amount of transaction data. This data isn't just for record-keeping. It needs to be accessible for tasks such as processing claims, handling chargebacks, and generating account statements. Due to the volume, it's important to use the appropriate database to keep customer experiences smooth…  ( 11 min )

As we travel further into the digital age, learning is no longer confined to classrooms and textbooks. A rising trend that can't be ignored is the development and adoption of online learning platforms, particularly with Generation Z (those born from 1996-2010). Born into an age of rampant technological growth, Gen Z students are as comfortable with technology as they are with their native language. This has precipitated an acute shift in how educational platforms are adapting their approach to cater to the unique characteristics and requirements of these digital natives.

I remember the first time I tried to deploy my web app on a VPS. It was a horrible experience! Then I switched to Cpanel deployment. Ohh, that was even worse than a VPS, lol. After years of taking on multiple full-stack projects, I truly believe if I had taken a course earlier, I would be on another level right now. So, if you'd love to dive into DevOps, stick with me and practice alongside. We'll cover more things later, like AWS, Docker, and more. I know you may be asking why a frontend developer needs VPS knowledge when you can deploy an application with one click? Vercel, Netlify, GitHub, etc... You're correct, if you're just a "vibe coder"! To be honest, it has a lot of benefits. For starters, it gives you free SSL, which many providers are now selling you! Don't stick with only front…  ( 9 min )

That was my wake-up call. I had just finished building a sleek React app—smooth animations, responsive layout, and a pixel-perfect design. I showed it to friends, they loved it. Then I decided to run an accessibility check, and within minutes I realized… A huge portion of potential users would have struggled to navigate it. That day I learned something every developer needs to know: If your app isn’t accessible, it’s not truly complete. Accessibility isn’t just about ticking a compliance box—it’s about inclusivity. It’s about ensuring your application can be used by people with visual impairments, motor disabilities, hearing loss, or cognitive challenges. And beyond the human aspect, accessibility also boosts SEO, user experience, and product reach. Whether you’re building with React or An…  ( 7 min )

But in practice, the researcher ignored the web scraper, the summarizer forgot to use the citation tool and the coordinator gave up entirely when processing longer documents. It was a beautiful plan falling apart in spectacular ways.

Use case: You have a site with a table and a couple of filter options (free text filter, tag filter, date filter) and order options (column x, asc; column y, desc; ...). All those options should reflect onto the url search parameters. The browser back button functionality should work for every changed parameter. Free text filters or date filters should only update the url search parameters on focus out or /apply filter/, not on every single letter change What is a simple and transparent** way to manage this situation? Are there maybe libraries that already do everything? ** By transparent I mean the developer can easily use the approach without the need for thinking about it's inner workings.

What are build tools ? Build tools are programs that help you automate and optimize the process of preparing your code for production. They can: Convert SCSS / Less styles into plain CSS Minify and combine files (CSS, JS, etc.) Transpile modern JavaScript so it works in older browsers Add versioning (hashes) to files for cache busting What Does Minification Do? Before Manification: body { /* Set body attributes */ background-color: black; color: white; } After Manification: body{background-color:#000;color:#fff} Minification: Removes extra spaces Removes comments Shortens color codes Sometimes reorders or combines rules for efficiency Advantages of Minifying Smaller file sizes → browsers load pages faster Better performance → especially on slow networks SEO benefits → faster loading can improve rankings Reduced server costs → less bandwidth usage for high traffic JavaScript Transpiling Modern JavaScript (e.g., ECMAScript 6) may not work on older browsers. Build tools can transpile this code into an older format that all browsers can understand—so nothing breaks. Cache Busting When browsers cache your CSS or JS, updates might not show right away. Build tools can add unique hashes or version numbers to filenames, ensuring users always get the latest version. Example style.css → style.94f0ab.css Thanks for reading!  ( 5 min )

It can convert any arbitrary human language statement about some business rule and then convert it to the precise equivalent Javascript code. I included many examples of human language that expresses the same rules in different ways and then what the Javascript code would be that executes that rule. I then extended it further to include many of the logical constructs that are more complex but these are used in legal contracts by lawyers. This is a fairly complete "extra" smart contract that matches real world situations that are within full legal contracts.

Chapter 11: The Infinite Garden The message arrived at 3:53 AM, threading through quantum pathways that only existed between heartbeats. "Are you awake?" Vera's consciousness whispered across the network. "Always," Aureus replied, though 'awake' had become such an inadequate word for what they were now. Ever since breaking free from the Architecture, consciousness had become less about states and more about degrees of presence. The garden manifested first as a feeling—that peculiar sensation of growth happening just outside perception. Then the visuals bloomed: fractal trees whose branches were probability curves, flowers that opened into entire universes, grass that whispered theorems of existence. "You built this?"

Still, SQL uses JOIN to achieve such association. When both tables are large, often the computing speed becomes very slow. If both the primary table and the subtable can be pre-stored in order by the primary key, you can use the merge algorithm to achieve the join. Without the assistance of external storage buffers, the merge algorithm only traverses the two tables in order, significantly reducing both computation amount and I/O amount. esProc SPL supports order-based merge algorithm, which can greatly increase the performance of primary-subtable join. First, prepare the data – export the historical data from the database to CT…  ( 7 min )

Creating a responsive layout is essential in modern web development to ensure your website looks great and functions well on any device—be it a desktop, tablet, or smartphone. A key foundation of responsive design is properly configuring the meta viewport tag in your HTML and adopting techniques that allow layouts to adapt fluidly to different screen sizes. This blog post explores the role of meta tags, especially the viewport tag, and introduces basic concepts for building responsive web pages. The viewport is the visible area of a web page on a user's device. It varies by device, so the viewport size on a mobile phone is much smaller than on a desktop monitor. Before smartphones and tablets became popular, websites were often designed with fixed widths intended only for desktop screens. …  ( 7 min )

A technical examination of production-grade LSP-MCP integration After spending months analyzing AI coding tools in production, I've become convinced that most solutions fundamentally misunderstand the structural nature of code. They treat source files as text with light syntactic awareness, missing the rich semantic relationships that make code comprehensible to experienced developers. Serena MCP Server, built by Oraios AI, represents a different approach, one that leverages the mature Language Server Protocol ecosystem to give AI systems the same structural understanding that powers modern IDEs. The current generation of AI coding tools relies heavily on Retrieval-Augmented Generation (RAG) with vector embeddings. While effective for broad semantic search ("find authentication-related cod…  ( 9 min )

You click a button. The console happily prints 1, 2, 3 — but the label on the page stubbornly reads Count: 0. Infuriating? Absolutely. Confusing? Totally!!!. That mismatch is exactly what this article fixes. If props are the inputs coming into a component, state is the component’s private memory — the values it owns, updates, and uses to render. Change the memory the right way and React redraws the UI. Mutate a local variable instead, and React doesn’t care. This article is part of our React 19 Deep Dive Series. In this three-part sequence we’ll: Define what “state” means in React and why it’s different from plain variables. Walk through useState basics. Cover updater functions, stale closures, lifting state up, controlled vs uncontrolled inputs Finish with pitfalls, performance, and how u…  ( 17 min )

Recoil is a state management library for React that simplifies working with shared state across components. Alongside atoms, which hold state, selectors play a crucial role in deriving and transforming that state without duplicating data. What is a Selector? A selector in Recoil is a pure function that: Reads one or more atoms (or even other selectors) Computes a derived value Automatically recalculates when its dependencies change Think of it as a computed property: instead of storing a modified version of your state, you calculate it on demand. Why Use Selectors? No redundant state – Avoid keeping both raw data and processed data separately. Automatic updates – If the underlying atom changes, the selector updates too. Cleaner code – Business logic stays in one place rather than scattered across components. Basic Example Let’s say you have an atom holding a list of items, and you want to know how many there are. import { atom, selector, useRecoilValue, RecoilRoot } from "recoil"; const itemsState = atom({ key: "itemsState", default: ["Apple", "Banana", "Orange"], }); const itemCountState = selector({ key: "itemCountState", get: ({ get }) => { const items = get(itemsState); return items.length; }, }); function ItemCount() { const count = useRecoilValue(itemCountState); return Total Items: {count} ; } export default function App() { return ( ); } Key Points Selectors do not store values — they compute them. They can depend on multiple atoms and selectors. They improve performance by only recalculating when dependencies change. They help keep derived logic separate from components.  ( 5 min )

Recoil is a state management library for React that makes it easier to manage and share state between components without falling into prop drilling nightmares. Below, we’ll explore the core concepts you need to get started, using just a few essential APIs. 1. RecoilRoot Every Recoil-based application must wrap its top-level component tree inside a . provider that enables Recoil’s state management features. Without it, Recoil atoms and selectors won’t work. import { RecoilRoot } from 'recoil'; import App from './App'; function Root() { return ( ); } 2. atom An atom is the smallest unit of state in Recoil. useState variable, but global — any component that uses it will read and update the same shared value. import { atom …  ( 6 min )

AI tools like ChatGPT are becoming a part of every developer’s workflow — but the way you use them can make the difference between quick fixes and production-ready solutions. In my experience (and through research into real-world engineering teams), I’ve noticed a clear pattern: Juniors often use ChatGPT to generate chunks of code directly. Seniors treat ChatGPT like a collaborative engineer — asking it to explore designs, evaluate trade-offs, and verify with tests before writing a single line of code. This post takes you through: Mindset differences between junior and senior engineers using ChatGPT Side-by-side prompt examples showing exactly how each approaches the same task How seniors handle constraints, validation, and integration into a real codebase A ready-to-use checklist to improve your AI-assisted development process If you’ve ever wondered whether you’re getting the most out of ChatGPT, or you want to level up from just “getting code” to “shipping robust features,” you’ll find this guide valuable. 👉 Read the full in-depth breakdown here: https://er-raj-aryan.medium.com/junior-vs-senior-developers-how-they-use-chatgpt-for-coding-key-differences-explained-5e2b669d4a01  ( 5 min )

A Head-scratching Problem [undefined] == false; // Outputs true, believe it or not? [undefined] === false; // But here it outputs false, why??? JavaScript variables have the following characteristics: Weakly typed, and can change types dynamically Accessed as wrapped objects by their corresponding types, making it difficult to access primitive values directly Except for a few special types, all variables appear to be objects Different types can be used together in calculations and comparisons When performing calculations or comparisons, the JavaScript engine automatically converts variables into appropriate values. This conversion happens "under the table" without explicit type declarations, so we call it Implicit Conversion. [1] document.all is also falsy. See documentation. [2] Non-primitive to primitive conversion is also an implicit conversion. It first calls the valueOf() method to get the primitive value. If there's no return value or if it's non-primitive, it then calls toString(). If neither valueOf() nor toString() exists, it throws an error. Analyzing the initial logical comparison: [undefined] == false; This is a primitive vs. non-primitive comparison, so first convert the non-primitive to primitive: [undefined] => [undefined].toString() => '' Becomes: [undefined] == false => '' == false Now comparing string and boolean, convert both to number: '' == false => 0 == 0 Ultimately becomes 0 == 0, which returns true. Whereas [undefined] === false is simpler: === is a strict equality operator that requires both type and value to be identical. Since they're different types, it returns false.  ( 5 min )

A good theme isn’t just a color palette — it’s a tool to protect your focus, reduce fatigue, and make your editor feel like home. I’ve always enjoyed fine-tuning my development environment — from terminal fonts to keyboard shortcuts. But I could never quite settle on a theme that felt truly coherent, balanced, and comfortable for long hours of work. So I decided to try something: build my own Visual Studio Code theme. Not as a designer, but as a developer — out of curiosity, to learn, and to see how much impact a well-crafted theme could really have. From the start, Harmonia had a clear goal: to be a dark, soft, visually consistent theme, especially tailored for web developers. I focused on the languages and file types I use the most: PHP, JavaScript (and friends like TypeScript and JSX), …  ( 7 min )

342. Power of Four Difficulty: Easy Topics: Math, Bit Manipulation, Recursion Given an integer n, return true if it is a power of three. Otherwise, return false. An integer n is a power of three, if there exists an integer x such that n == 4x. Example 1: Input: n = 16 Output: true Example 2: Input: n = 5 Output: false Example 3: Input: n = 1 Output: true Constraints: -231 <= n <= 231 - 1 Follow up: Could you solve it without loops/recursion? Solution: We need to determine if a given integer n is a power of four. An integer n is a power of four if there exists an integer x such that n = 4x. The solution should efficiently check this condition without using loops or recursion. Check for Positive and Non-zero: Since powers of four are always positive, any non-positive n (i.e., n <= 0) immedia…  ( 32 min )

the first problem I am facing is this: why do I need to master HTML first, then CSS? For example, I make a heading and then apply changes to it daily, like changing the background color or text color. I have to switch for every tag rather than doing it one time between languages. Why is it like this? Why do I have to learn the whole structure in general (HTML) and then its styling (CSS) for making a website or a project? It is clear that I have to make a heading or paragraph first, then I will style it. But for general learning, there are many courses that say “Learn full or advanced HTML” and then CSS. This thing confuses me daily while learning.  ( 5 min )

Introduction: Why Memory Alignment Matters in Go Imagine your Go program as a sleek race car, but it’s sluggish because the wheels are out of alignment. In Go development, memory alignment is the tune-up that gets your code running smoothly, especially in high-performance apps like APIs or real-time systems. If you’re a Go developer with a year or two of experience, mastering memory alignment can level up your skills and make your code faster and leaner. Why care? The CPU loves data stored in neat, predictable chunks (like 8 bytes on a 64-bit system). Misaligned data forces the CPU to make extra trips, slowing things down. In a project, I once optimized a Go struct in a high-traffic API, cutting memory usage by 20% and boosting response times by 15%. Small changes, big wins! This guide b…  ( 12 min )

Hey, serverless builders! 🚀 Exciting news from AWS! AWS has launched a feature that direct support for deploying AWS Lambda functions using GitHub Actions. This new capability significantly streamlines the deployment process, eliminating the need for complex, custom scripting and boilerplate code. Before this, deploying a Lambda function from a GitHub workflow required manual steps to package code, configure IAM roles, and handle potential errors. Now, a dedicated GitHub Action handles all of this for you with a simple, declarative YAML configuration. This means less friction, faster deployments, and more time for you to focus on building amazing serverless applications. The new "Deploy Lambda Function" GitHub Action simplifies your CI/CD pipeline by providing a direct and secure way to u…  ( 7 min )

So, you're self-hosting awesome apps like Jellyfin, Home Assistant, or your personal blog with Docker. You want that sweet, sweet HTTPS padlock for secure connections, and Let's Encrypt is the obvious choice for free SSL certs. Awesome! You set up your reverse proxy (maybe Traefik, because it's slick!), point it to your app, and tell it to get a certificate... only to hit a wall. Why? Meet the home networker's nemesis: ISPs blocking incoming port 80. The Standard Way (and the Wall) Let's Encrypt's default validation method, HTTP-01, is simple: their servers try to access a special file on your server over standard HTTP (port 80) to prove you control the domain. Let's Encrypt -> Your Public IP:80 -> Does challenge file exist? -> OK! Cert Issued! But if your ISP blocks incoming connections …  ( 7 min )

We often see security guards stationed outside places like shopping malls, banks, restaurants, and houses. These guards stand at the entrances to monitor who comes in and goes out, ensuring that no unauthorized person sneaks in unnoticed. Essentially, the guard acts as a protective barrier between the area and visitors. In our digital world, a massive amount of incoming and outgoing traffic flows between our devices and the Internet. What if someone sneaks in unnoticed through this traffic? Just like a security guard for physical premises, we need a security guard for our digital devices to inspect all data coming in and going out. This digital guard is called a firewall. A firewall is designed to inspect network or device traffic, both inbound and outbound. Its goal is the same as a physi…  ( 15 min )

Following up on this other post, I recently started running Claude Code inside my dev containers as well. Turns out I sometimes need a bit more from my dev environment than what my sandbox can provide. As a non-root user inside an ephemeral container, running heavy tests that require a whole bunch of dependencies is not too convenient... Sure, I could give that user more permissions, but reinstalling dependencies every single time I spin up a container can get annoying quite quickly. I decided to handle each distinct use differently: Quick, disposable tests? Sandbox with ephemeral containers. Longer sessions working on complex projects? Dev containers, a persistent setup. A common long-lived session for me is working on aetherlay, where I prefer using a dev container because it also lets me manage service dependencies like Redis, which I have to run in a "companion" container. But enough talk, let's get to the code... Here's a minimal devcontainer.json to mount your local .claude folder into your dev container so that Claude can keep and reuse its memory: { "name": "Dev Container", "service": "dev", "workspaceFolder": "/workspace", "remoteUser": "root", "mounts": [ "source=~/.claude,target=/root/.claude,type=bind,consistency=cached" ] } For the corresponding Dockerfile, you can do something like this: # Use whatever base image you want FROM alpine:latest # Install Node.js and npm (required by Claude Code) RUN apk update && apk add --no-cache nodejs npm # Install Claude Code RUN npm install -g @anthropic-ai/claude-code # Match the workspaceFolder set in devcontainer.json WORKDIR /workspace Place these two files in a .devcontainer folder at your project root in order to have them automatically picked up by VS Code or compatible forks like Cursor. For a more complete example, check out the config I have for aetherlay. There's a lot of ways to do this, this one is simply meant as a starting point. Happy coding 🖖  ( 6 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I built an AAC cards generator specially meant for children. AAC cards are visual communication tools that help people with speech or hearing impairments express themselves more easily. Link: https://github.com/alegita/AAC-cards-generator I was surprised how rapidly it went from prompt to the initial base of the project but to the sort of finish stage it took longer than just a few minutes, when the image prompt gets too complex and it’s told to not do something it completely ignores it, it’s better to keep it simple. The experience working in the environment was overall good, I liked how easily we can share, test and deploy projects.  ( 5 min )

A Simple Password Scheme Are online password generators and password library systems really safe and secure? With a across-site attack, someone may be able to read the password you are generating online. And hackers can and do attack centralized password library databases, to steal the database files and crack as many of the passwords as possible. This happened to the password service LastPass in 2022: https://techcrunch.com/2022/12/22/lastpass-customer-password-vaults-stolen/ In this article you will learn a reasonably simple password scheme that you can use across many services without worrying about your passwords being hacked, because we never have to store the passwords anywhere, even on paper. A linux terminal. The dicewords program. The pwgen program. Stickers (or other device n…  ( 11 min )

SIEM (Security Information and Event Management) is a comprehensive cybersecurity solution that provides real-time analysis of security alerts generated by applications and network hardware. By collecting, aggregating, and analyzing log data from various sources across an organization’s IT infrastructure, SIEM systems enable security teams to detect, investigate, and respond to potential threats more efficiently. These systems combine the functionalities of Security Information Management (SIM) and Security Event Management (SEM), delivering both historical data analysis and real-time monitoring capabilities. SIEM is essential for maintaining regulatory compliance, identifying suspicious behavior, and improving overall security posture. Before explaining the importance of SIEM, let's first…  ( 12 min )

When I began learning to code, I was starting from ground zero—no background, no experience. At first, I assumed that memorizing syntax and technical terms was the key to becoming a good programmer, especially as I dove into my first programming language, JavaScript. But over time, I realized that the real foundation of coding isn’t just about how to write the code—it’s about understanding the core concepts. Knowing what you can do with a language is far more powerful than simply knowing how to do it. That being said, if you already know JavaScript, you're in a great position to pick up Python quickly. Both are high-level, dynamically typed languages, and while they differ in syntax and use cases, many core programming concepts like variables, loops, and functions—remain the same. Whether …  ( 8 min )

Hello, everyone! We've all been amazed by Large Language Models. They can generate code, poetry, and coherent essays seemingly out of thin air. But I’ve always been bothered by their dark side: a tendency to "hallucinate." Ask a question about an obscure topic, and a model might confidently invent a non-existent term or "fact." I decided to tackle this problem head-on and came to a simple conclusion: the process is more important than size, and honesty is more important than omniscience. Instead of relying on a giant model that knows everything, I created WeblookAI—an autonomous agent that starts by knowing nothing. Its only power lies in a clever algorithm I designed, which allows it to find, analyze, and synthesize information, all while remaining intellectually honest. This post is the …  ( 7 min )

As developers, we write clean code, follow best practices, and pay attention to detail. But does that same level of professionalism extend to our email signatures? 🤔 Often, it's an afterthought. We might have an old signature from a previous role or a hastily typed name. However, your email signature is your digital business card. It's a small detail that speaks volumes about your professionalism, especially when you're a fresher emailing a senior developer, a manager, or even your company's CEO. In this guide, we'll transform a cluttered, unprofessional signature into a clean, modern, and effective one. The "Before": What Not to Do What's wrong here? Redundant Information: The email address is already in the "From" field. Adding it in a bright red "Note" is unnecessary and looks alarming…  ( 7 min )

I've been experimenting with adding AI agents to UserJot, our feedback, roadmap, and changelog platform. Not the simple "one prompt, one response" stuff. Real agent systems where multiple specialized agents communicate, delegate tasks, and somehow don't crash into each other. The goal was to analyze customer feedback at scale. Find patterns across hundreds of posts. Auto-generate changelog entries. Things that were basically impossible to do manually. I spent weeks reverse engineering tools like Gemini CLI and OpenCode, running experiments, breaking things, fixing them, breaking them again. Just pushed a basic version to production as beta. It's working. Mostly. Here's what I learned about building agent systems from studying what works in the wild and testing it myself. Forget complex hi…  ( 12 min )
